Release notes

v3.12.1

  • Enhancement: Reduced the number of times the constraint layer was being refreshed when changes occurred.

  • Enhancement: Constraint layer visibility now stays on or off depending on the state of the layer prior to an action taken (e.g. user makes a new constraint, edits an existing constraint, or deletes a constraint). This makes the visibility of the constraint layer consistent with what the user had set it to and removed the default visibility that was set to be always on after an action occurred.

v3.12.0

  • Enhancement: Added an optional setting for specific users to have the parcel constraint layer automatically turned to off when loading the constraint menu. This helps a small subset of users that have large and complex constraint geometries from having to wait for the layer to load before any action could be taken.

  • Fixed an issue from v3.9.0 where the constraint zoning code attribute would not show up in the attribute sidebar when constraint polygons were queried on the map.

  • Reverted the v3.9.0 fix for the simple symbology fill color picker box which made the outline color picker fail to open. The simple symbology fill color picker box is now hidden under the header of the layer form as it was prior to v3.9.0 until a future fix can be made.

v3.11.0

  • Enhancement: Constraint FAR/Plot Ratio input boxes now will accept any number of decimal places instead of only 1.

  • Fixed an issue from v3.9.0 where the attributes of constraints were not showing up in the attribute sidebar when polygons were queried while using the categorical symbology option on the constraints layer.

  • Fixed an issue from v3.9.0 where if a categorical symbology was set and in use by the constraint layer, any change to constraints would reset the constraint symbology back to the default simple symbology.

v3.10.0

  • Fixed an issue impacting a small subset of users where the comment CSV was not available for download when comments existed.

v3.9.0

  • New feature: Added new Zoning code field to parcel model constraints. Parcel model constraints can now have a specific zoning code designation for reference purposes.

  • New feature: Parcel model constraints can now be symbolized using the categorical Zoning code field. This allows for replicating official zoning color codes for ease of map data interpretation.

  • Fixed an issue impacting a small subset of users where comments were unable to be loaded on the map.

  • Fixed an issue that would occur with the symbology color picker being hidden underneath the header of the display options form when using the simple symbology option.

  • Fixed an issue where the existing selected polygons for a development project, constraint, or adjustment was not being shown on the map as green polygons when in edit mode. Existing selected polygons are shown as intended.

v3.8.0

  • New feature: Subscribers with Viewer roles now have the ability to configure the chart dashboard for use by viewers.

  • Enhancement: Added the control key as a option for deselect mode when selecting polygons for development projects, constraints, and adjustments. To deselect specific polygons that have already been selected hold down the control or alt key and click on the polygon to deselect.

  • Enhancement: Reduced the memory footprint of the data upload validation service which has resulted in a significant speedup of validation run times and reduces the risk of exhausting computing resources.

  • Enhancement: Minor updates to the UrbanCanvas user interface to address compliance with Web Content Accessibility Guidelines (WCAG) 2.0, Level AA.

  • Enhancement: New user account confirmation page now displays a title and UrbanSim logo to better inform the user about what page they are currently on.

  • Enhancement: Added an extra indicator to the Admin invite user form that will inform you if the user’s email address you are attempting to invite has already been sent an invitation.

  • Enhancement: Account Manager user profile page has been updated to remove red asterisks on fields and clarify labels on the change password form.

  • Fixed an issue that would occasionally occur with indicator layers where the years were not sorted in ascending order in the year dropdown menu or the time slider. Years sort correctly now.

  • Fixed an issue with the labels in the parcel model constraint form for regions that use plot ratios, the labels for min and mix plot ration in the input box had the incorrect names. Similarly, labels for the max and min DU per HA section were corrected.

  • Fixed an issue with the conversion of parcel and block model constraint area units for DUA/DU per HA and EDA fields. Units are now correctly being converted between imperial and metric systems.

  • Fixed an issue that was not allowing existing UrbanSim users to accept invitations to other regions. When accepting invitations users would not be able to proceed past the accept invitation screen.

  • Fixed an issue in the Account Manager subscription tab where the subscription contact information was not able to save edits correctly.

  • Fixed an issue in the Account Manager that would sometimes occur when updates to the user interface were not being shown in the browser correctly due to an issue with caching.

  • Fixed an issue that would sometimes occur in the Account Manager where the incorrect date would be displayed when viewing a user’s invitation status.

  • Fixed an issue with public viewer roles where the links in UrbanCanvas to manage your settings were not redirecting you to the correct tab in the Account Manager. Also added, a manage settings dropdown menu to the Account Manager right-hand side menu for public viewer roles.

  • Fixed an issue where the label for parcel model scenario vacancy rates by building type dropdown menu was incorrect.

  • Fixed an issue that would occur when using the filter feature for development projects, constraints, and adjustments that would not filter the records on the map to match the set filter.

v3.7.0

  • New feature: Added optional two-factor authentication via smart phone authentication application. Two-factor authentication can be enabled or disabled inside of the security tab of the account manager.

  • New feature: Quantity layer symbology has been updated to more accurately generate break points for the number of requested bins resulting in a more accurate representation of the distribution of values in the layer. This update also specifically creates a bin for values that are 0 or less than 0. Prior to this update, values less than 0 were not represented in the resulting distribution.

  • Enhancement: Categorical layer symbology now treats null values as a category that can be added or removed from display. Prior to this, null values would be displayed as red polygons on the map.

  • Enhancement: Updated the UrbanCanvas username or email login form invalid character recognition to help avoid common username and email mistypes.

  • Enhancement: Updates made to the simulation and UrbanCanvas interface to reduce the likelihood of simulation failure due to intermittent connectivity issues.

  • Enhancement: Updates made to the simulation and UrbanCanvas interface to print in the simulation log any issues that are found when the simulation exports indicators to UrbanCanvas. The more detailed data validation information were being hidden from the log.

  • Enhancement: Added support for Australia localization of constraint labels in create and edit constraint window, constraint table, and attribute cards including updating constraint metric labels for DUA to DU per Hectare for clarity.

  • Fixed an issue that was affecting a specific zone model user using metric units where the scenario inputs from UrbanCanvas were being received in imperial units resulting in the simulation receiving unexpected column names.

  • Fixed an issue that would occur when changing an existing layer’s symbology from simple and or quantities to categorical, the categorical layer that would be displayed would not have all the available category values populated on the map.

  • Fixed an issue that was not showing the attributes of polygons queried for time series indicator layers. Querying time series indicators now works as intended.

  • Enhancement: Increased resources allocated to data upload validation service to accommodate very large skim files upwards of 5 GB in size. Files this large would cause the service to exhaust resources and fail.

  • Fixed an issue introduced in v3.6.0 related to how layer metadata was being read that would occur when displaying certain layers on the map, affected layers would not show up on the map.

  • Fixed an issue with parcel model edit and create constraint form that was preventing input in the allowed building types selector from being saved.

  • Enhancement: Miscellaneous security updates.

v3.6.3

  • Fixed an issue with zone and parcel models where the polygon selection tool for creating or editing development projects, constraints, and adjustments was not selecting zones or parcels correctly. This has been fixed and a loading indicator has also been added to notify user when the polygon selection process is running and has completed.

v3.6.2

  • New feature: Added CAPTCHA system from reCAPTCHA to the UrbanCanvas and account manager login pages.

v3.6.0

  • New feature: Added new Mapbox Terrain feature to the map which allows you to visualize 3D terrain with basemaps and map layers offering greater topographical context. Turn on and off terrain from within the map layer basemap menu.

  • Enhancement: Implemented a new map layer tile service to help balance server loads when a large number of map layer tile requests are made at the same time to prevent bottlenecks in map layer rendering. Layer rendering under large loads can be expected to be up to 4x faster than before.

  • Enhancement: Layers with small polygons viewed at coarse zoom levels displayed using the quantities symbology would sometimes appear with holes or missing polygons that would not be rendered. This has been fixed to ensure all polygons using the quantities symbology are rendered properly at coarse zoom levels.

  • Fixed an issue that would occur when querying small polygons in indicator map layers at coarse zoom levels where no attributes would be returned and the attribute panel would freeze.

  • Fixed an issue that would occur intermittently when requesting data or status updates in UrbanCanvas that resulted in the error Cannot read property getModels of undefined.

  • Fixed an issue related to Mapbox that would occur when changing the basemap, when a new basemap was selected any map layers that were turned on would turn off.

  • Fixed an issue introduced in v3.5.0 where development projects that do not use AMI attributes will have null AMI attributes shown in the attribute side panel when queried on the map. Now only development project AMI attributes that have non-null AMI attributes will be shown.

  • Updated the parcel model development project attribute field description for non-residential space that was changed in v3.5.0 to the correct description.

v3.5.1

  • Fixed an issue introduced in v3.5.0 where decimal places were not being allowed in phased attribute percent input fields for development projects.

  • Fixed an issue that was preventing emails with reset password links to be sent when requesting a password reset.

v3.5.0

  • New feature: Updated Account Manager Settings page

    • Added settings that are configurable by region administrators to establish default base map, system of measurement used in the user interface, and date and time formats.

    • Added settings that are configurable by users of a region to change the default system of measurement and date and time formats used in the user interface.

    • Settings tab also shows the default map latitude and longitude center, map zoom level, spatial reference system, model template, base year, model system of measurement, residential vacancy rate, and time zone used in the user interface. These settings currently cannot be changed and are provided only as a reference.

  • New feature: Date and time format display setting

    • All date and time stamps shown in the user interface can now be customized to be shown in a specific format. Change the format of each type of date and time stamp from within the Settings tab in the Account Manager.

  • New feature: Measurement system display setting

    • The measurement system displayed in the user interface can now be customized to be either imperial or metric. Change the displayed measurement system from within the Settings tab in the Account Manager. Changing from imperial or metric will only change the units that are displayed in the user interface or for data downloads not related to the simulation. The simulation will continue to operate in the measurement system native to the model base data and all inputs sent to the simulation and all outputs from the simulation will be in the model’s native measurement system.

  • Enhancement: Updates made to the confirm UrbanSim account and confirm account invitation page to display more helpful error messages when: 1) user invitation has expired; 2) user has attempted to accept an invitation that the user had already accepted; 3) user attempts to accept an invitation that has been canceled by the admin.

  • Enhancement: Updates made to the create UrbanSim account page where:

    • Repositioned form validation warnings so popups do not interfere with the position of input boxes.

    • Repositioned username and email input boxes and added autofill to username based on email.

    • Updated address input box text for ‘Zip’ to ‘Zip / Postal Code’ and ‘State’ to ‘State / Province’

  • Enhancement: Updated color contrast within the UrbanCanvas user interface to support Web Content Accessibility Guidelines (WCAG) 2.0, Level AA compliance.

  • Fixed an issue that would occur when editing adjustment records where not all existing attributes of the adjustment would appear in the adjustment form.

  • Fixed an issue introduced in v3.0.0 where simulation downloads were not sorting correctly for files that were associated with a simulation year.

  • Fixed an issue with Viewers not being able to see the correct Account Manager shortcut links in the right hand dropdown menu in UrbanCanvas, the following additional links have been added: Subscription, Permissions, and Settings.

  • Fixed an issue when a user invited to an UrbanCanvas region had no first and last name, the accepted invitation notification email would display the user’s name as null. If no name exists for the user, the username or email address will be displayed instead.

  • Fixed an issue in Account Manager Users tab where existing users that did not have a first and last name would show up in the Users table as None. Now the username will be displayed if no name is available.

  • Fixed an issue in Account Manager Users tab where search would return no results when a user did not have a first or last name, now email address will return as a result if name does not exist.

  • Fixed an issue that was not sending the email notification to user when their user role had changed.

v3.4.0

  • New feature: UrbanCanvas and validation service now supports household control totals that have an optional total_number_of_people column to control for the exact number of persons within households. This is only supported for UrbanSim models that have been configured to use this information.

  • Enhancement: Simulations now utilize an independent token from your UrbanCanvas login session which allows simulations to continue running even if your user login session token had expired. Simulations can now run for a maximum of two weeks without needing a token renewal.

  • Fixed an issue that would occur during password reset where after confirming your new password, the page would attempt to redirect to UrbanCanvas but it would hang indefinitely on the redirect message popup.

  • Fixed an issue in the Account Manager that would not display the MPO ID or Base Year in the tooltips on the Your Regions page.

  • Fixed an issue with the adjustment record filter feature when filtering by tags. Records on the map were not being filtered when the filter was applied.

  • Fixed an issue that could occur when uploading TAZ files that have large integer values in the ID column. ID column values would show up as null.

v3.3.1

  • Fixed an issue affecting Single Sign-On (SSO) users on Firefox browsers that was not allowing the user to logout of UrbanCanvas correctly.

  • Fixed an issue with the Block model zoning to constraint converter tool that was allowing multiple tags to be selected in the form. Only one tag can now be selected.

  • Fixed an issue with the Block model zoning to constraint converter tool that would fail to run with a ReferenceError: request is not defined error.

  • Fixed an issue with simulations returning: TypeError: Cannot read property ‘roles’ of null and TypeError: Cannot read property ‘getModels’ of undefined errors.

  • Fixed an issue introduced in v3.0.0 where dropdown selectors in the UI that allow selecting uploaded files were allowing users to select all uploaded files of that type regardless if the file had passed upload validation. Now only files that passed upload validation are available for selection in these dropdowns.

v3.3.0

  • New feature: UrbanCanvas and validation service now supports the upload and data schema validation of zone and parcel model zoning shapefiles.

  • Enhancement: Parcel model scenario form for the base data collection field now shows a new default option to use the Default model configured h5 file that is specified in your model codebase repository instead of using a base data collection uploaded to UrbanCanvas. This means that an UrbanCanvas base data collection is no longer required input to build a scenario.

  • Enhancement: Optimizations have been made to the UrbanCanvas map layer rendering workflow that result in significant layer rendering performance gains when multiple layers that are large in size are requested at the same time.

  • Fixed an issue that was not correctly rendering superscript notation in the search column selection dropdown menus. This issue affected zone model users with metric system units.

  • Fixed an issue introduced in v3.0.0 where the run inspector window was displaying the name of the scenario the run was associated with in the window title instead of the run ID.

v3.2.2

  • Fixed an issue that was not allowing certain map layers to be extruded.

  • Fixed an issue introduced in v3.2.0 that was invaliding the communication between a running simulation and UrbanCanvas if the user had logged out while a simulation was running. Issue would show up as Error: JWT not found in authentication whitelist in the simulation log.

  • Fixed an issue that could occur when uploading TAZ files that have values in the ID column that are greater than 4-bytes. The upload would fail if values were over 4-bytes.

  • New feature and enhancements: Upload validation updates

    • Added support for metric units in parcel model tables and support of storeys as an optional replacement for the stories column.

    • Some validation messages have been truncated to show only the first 20 records of data that have errors in order to reduce the amount of text.

    • Support added for both integer and string type serialno columns.

    • Increase column name character limit from 31 to 63.

    • Changed building footprint geometry validation of height column values to a warning to allow negative placeholder values.

    • Removed constraint on uploads that enforced no digits in the first character of a column name.

    • Added a new data type and length validation check for known US and Canadian census ID columns.

    • Various updates to validation message clarity including for control totals that contain duplicate years and skims.

    • Optimizations made for performance and run time.

v3.2.1

  • Fixed an issue introduced in v3.2.0 that was removing certain characters from the username/email login field on the login page such as dashes -.

v3.2.0

  • New feature:

    • Added support for Single Sign-On (SSO) via Microsoft Azure Active Directory (AD). UrbanCanvas subscription holders who utilize Microsoft Azure AD for SSO of their applications can now access UrbanCanvas as a non-gallery Enterprise Application. SSO for UrbanCanvas via Microsoft Azure AD can be provided for subscription holders as part of your subscription agreement. Contact info@urbansim.com for more information on how to get access to UrbanCanvas on Microsoft Azure AD.

  • Enhancement: Updated the UrbanCanvas username or email login form to remove spaces and convert characters to underscore to avoid common username and email mistypes.

  • Enhancement: Updates to the UrbanCanvas user interface have been made to bring the application up to Web Content Accessibility Guidelines (WCAG) 2.0, Level AA compliance.

  • Enhancement: Updates made to enhance the security of the user logout function and invalidation of user login session.

  • Enhancement: Added the unique UrbanCanvas region ID to the region switch tooltip to provide more information on what region a user is currently viewing and to the account manager My regions information tooltip.

  • Enhancement: When switching between regions, the region switch dropdown menu will by default first show you region you are currently in.

  • Fixed an issue that would create market_rate_units_null and affordable_units_null columns in the development project report CSV if a project had at one time but no longer had market or affordable units that were phased over time.

  • Fixed an issue in the parcel model scenario form that was not showing the warning to the user that the base data collection field was required if it was missing. The form would not save unless a collection was specified, the correct warning now appears as intended.

v3.1.2

  • Fixed an issue that was causing table records on the upload page to not update in realtime.

  • Fixed an issue some users experienced with new simulation runs when trying to download simulation results. Users would encounter error: Anonymous caller does not have storage.objects.get access to Google Cloud Storage object.

v3.1.1

  • Fixed an issue related to simulation retrieval of travel model network files that would cause simulations to fail after log line: Downloading Travel Model Data Networks… if using scenarios with travel model network files.

v3.1.0

  • Enhancement: Null values are now allowed as a category when using the map layer categorical symbology option.

  • Enhancement: Updated the UrbanCanvas password policy to enforce stronger user passwords with a minimum of 12 characters and contain at least one upper, lower, and numeric character.

  • Enhancement: Added a password reveal button to all locations in UrbanCanvas where passwords are entered to allow users to double check the entered password.

  • Enhancement: Logging out of the account manager now redirects you to the main UrbanCanvas login page instead of the account manager login page.

  • Fixed a configuration issue that was incorrectly limiting server communication timeouts to 30 seconds. Typically, the issue would occur while uploading very large files to UrbanCanvas and the upload process would fail if it took longer than 30 seconds.

  • Fixed an issue that was preventing users from deleting uploaded skim files.

  • Updated the calculation of polygon areas for development projects, constraints, and adjustments to use the specified local projected spatial reference system for the region.

  • Fixed an issue that would cause failures while uploading shapefiles if the projection of the file was using a projected spatial reference system. An error starting with: Error 1 proj error internal proj would occur.

  • Fixed an issue that was not allowing travel model network files of type both to be uploaded correctly. Upload would stall on Uploading data.

  • Fixed the display of the percentage of records intersected for certain uploads such as TAZ and summary files where the percent intersected would appear to be inverted.

  • Fixed an issue introduced in v3.0.0 with the development project table search related to the program column that would not find certain records with the specified search term when records should have been returned.

  • Fixed an issue in the chart table when searching for values in the created by column that was case sensitive, search is no longer case sensitive for this column.

  • Fixed an issue that was re-running data validation on parcel model base data collections when only the metadata of the collection had been edited. Now data validation is only re-run if data tables in the collection are changed.

  • Fixed an issue in the parcel model base data viewer table for parcels and buildings that would sometimes duplicate the primary ID columns: primary_id and building_id.

v3.0.3

  • Fixed an issue where users that had access to multiple UrbanCanvas regions were not able to switch between regions. The switch would fail with an error message.

v3.0.2

  • Fixed an issue that impacted existing users whose invitation to a new UrbanCanvas region had expired and a new invitation was sent, the new invitation was incorrectly registered as expired and they would not be able to accept the new region invitation.

v3.0.1

  • Fixed an issue on current Public Viewer accounts that was not correctly loading the default symbology options saved for a layer when layer was displayed.

v3.0.0

  • Released a major behind the scenes refactor of the user interface to support a new version of the JavaScript framework used for the user interface.

  • Fixed the duplication of the primary_id column in the parcel table in the base data viewer.

  • Fixed an issue with the layer attribute table when using the search option to find a string that is composed of all numbers, search would not find records.

  • Fixed an issue in the categorical layer symbology form that was not allowing the select and deselect all buttons to work correctly.

  • Fixed an issue in the categorical layer symbology form categories table that was not allowing the count columns to sort correctly.

  • Fixed an issue in the categorical layer symbology form that was not allowing you to add new categories to the selected categories table after you had updated an existing category’s symbology.

  • Fixed an issue in the charts dashboard that in some instances would allow you to overlap charts on top of each other.

  • Added a syncing dashboard indicator when loading a chart dashboard to avoid issues with being able to modify a dashboard before it had been fully synced.

  • Fixed an issue in the base data viewer where the collection search was not working correctly and also was case sensitive, search is no longer case sensitive.

  • Fixed an issue in the scenarios table that would occur when you had a search term applied or a filter applied on a table and your table view would reset when editing a record in your selection set. This has been fixed to work as intended to keep your selection set in view even when edits are made.

  • Addressed a number of issues related development projects with 0 or null attribute values not being saved or displayed as 0 or nulls in the table. Now records are saved with either 0 or null depending on what was specified in the field.

  • Fixed an issue that was not allowing the runs table columns: scenario id, scenario name, and calibrated coefficient to sort.

  • Fixed an issue that was not correctly applying the opacity symbology setting on map layers when using the Base polygon option on extruded layers.

  • Fixed an issue in the base data viewer when viewing tables connected to map layers, any changes to symbology for those layers were not being saved to your user session and when they were reloaded in a new session the symbology would revert to the default settings.

  • Updated the behaviour of the filter table record form to now clear the values set in the value box when you change the filter by type. Prior to this, the values would be preserved when changing the filter by type which would potentially cause an inconsistency.

  • Reduced the number of rows displayed by default with pagination for development projects, constraints, and adjustments from 50 to 20 records which results in a significant table loading speed improvement and responsiveness especially when a search term is applied.

v2.5.3

  • Fixed an issue that was not allowing administrator accounts that did not have an email address to send new user invitations or change user roles.

  • Fixed an issue that may have affected some simulations with a KeyError: “injectable not found: ‘year’” error which was related to the format of development project scenario data that was sent to the simulation.

  • Fixed an issue related to server resources devoted to certain file uploading operations that may have affected some users when uploading indicator CSV files.

  • Fixed an issue with the chart table that would result in an error when a record would be deleted and the table was sorted by any column other than the ID column.

  • Fixed an issue that was not allowing the min and max value threshold option to work correctly when symbolizing indicator map layers.

  • Fixed an issue where some simulations would download scenario skims as type .zip instead of type .csv.

  • Fixed an issue with simulation start and end timestamps in the runs table when a simulation failed during initialization or from exhausting computing resources. The start and end times are now populating as intended.

  • Canceling a simulation run now works as intended and will cancel the run successfully.

  • General improvements made to the categorization, verbosity, and logging of error messages in the simulation service including:

    • More descriptive errors are now returned when scenario data cannot be found.

    • Improvements have been made to logging and retries when there are intermittent connection issues between UrbanSim simulation services.

    • Simulations that fail due to issues installing Python dependencies will now fail correctly returning a failed status.

    • Simulations that failed during initialization or that ran out of computing resources during a run will now correctly have their status set to failed instead of running. The log for these types of failures will also now be populated with the last log output to aid in debugging.

v2.5.1

  • Fixed an issue that was not allowing admins to save changes made to what layers were turned on and off in the account manager layer permissions table.

  • Admins with Viewer accounts can now turn on and off the layer attribute table for Viewer users in the UrbanCanvas user interface.

  • Fixed an issue that was introduced in v2.5.0 that was not properly scaling time series indicators values to the min and max of value of the time series when the scaling option was turned on. Min values for the layer were showing up as nan.

  • Fixed an issue that was introduced in v2.5.0 that would occur when exporting indicators from a simulation that resulted in: Error: Filetype or Name not defined.

v2.5.0

  • New Feature: Added new user role permission options for layers to turn on and off layer symbology editing and layer removal from the layers panel.

  • New Feature: Added new user role permission options for the layer attribute menu to turn the feature on and off.

  • New feature: Admins can set and save a default symbology for map layers for individual layers and fields within the layer for all symbology types. Modelers and Viewers cannot set a default symbology but can change the symbology as needed if edit permissions are granted. When added to the map by other users, layers and fields that have a saved default symbology will have defaults set to the saved settings.

  • Email notifications sent to admins are now set as BCC to hide the email addresses of the other admins on you account.

  • Fixed an issue that occurred when switching between different regions in the account manager that was not displaying the selected region’s subscription information in the subscription tabs. It was showing the default region for the user instead.

  • Fixed an issue that would occur when changing an existing development project from a residential project to a non-residential project or visa versa where the old building type attributes would be preserved on the record’s attribute table. Now if the building type is changed, the attributes not related to the new building type are removed when saving.

  • Updated admin user removal action when admin removes a user from a specific region, that user is now removed from only that region instead of from all regions associated with that user.

  • Removed the create account button from the account manager login page. Accounts are now only allowed to be created if joining a Public Viewer UrbanCanvas region or if invited to an existing UrbanCanvas region.

  • Updated user region removal and role change email notifications to display the name of the region that the change occurred in.

  • Fixed an issue in the chart dashboard that would cause the rendering of Altair histogram charts to not appear correctly. Also enhanced Altair chart layout rendering for better visualization and appearance of chart components.

    • Increased timeout for uploads to handle extremely large files.

v1.27.0

  • New feature: Indicator CSV uploader

    • New section added to the uploads page for uploading CSV indicators. This uploader uses the same method used to automatically upload indicators from simulation runs and is provided as a convenience to upload ad-hoc indicator layers. Indicators must be a time series CSV file and can be linked to an uploaded shapefile to use as the indicator geometry.

  • Update: Indicator layers uploaded by simulation are now available as records in the new indicator uploads section where:

    • You can now delete and rename indicator layers.

  • Update: Time series indicators with all null values for specific fields and years will not have those years populated as an option to select in the layers menu or time slider.

  • Update: Block model development projects that use phased attributes now have those phased attributes available for use by a simulation if the simulation has been configured to use it.

  • Optimized the creation of development project, constraint, and adjustment records that contain large and very complex multipolygons.

  • Fixed an issue where renaming an uploaded file that was set as the core base data layer would rename both the map layer for the upload and the core base data layer. Now only the layer name for the uploaded file is renamed.

  • Fixed an issue with zone and block model adjustment records for job spaces and non-residential space not being in the correct expected format if used in a simulation.

  • Fixed an issue affecting some drop down menus in the user interface that were not populating saved information. Specifically, this fixes an issue in the scenario form drop down menus, such as control totals, that were loading as blank when looking at existing scenario records or using the based on function.

  • Map legend updates:

    • Updated the legend shown for categorical layers to remove the extra white space padding around the edges of the legend.

    • Updated legend z-order to always be underneath the main menu.

v1.26.0

    • Indicator map layers with more than one year have the option to be viewed as a time series in a time slider. A new time slider box is available for time series enabled layers where each year of the time series is displayed as a tick mark on the time slider line. Dragging the marker back and forth across each tick on the line updates the data shown on the map for that layer for the specified year.

    • Time series indicator layers in the time slider have the option to scale values in the time series by the min and max value of the entire time series so that the distribution of values is held constant while viewing each time point in the series.

  • New feature: Comments

    • Added a new Comments button on the UrbanCanvas header to toggle comments on and off the map.

    • New comment icons to add a comment to the map and confirm location have been added to the map view underneath the map navigation icons.

    • All UrbanCanvas Modeler users can interact with and see comments and comment histories in your account. Only comment or reply authors can edit their authored comments or replies.

  • New feature: Simulation logs in the run status window now have the option to show: 1) a simple log - the same abbreviated log shown prior to this update; or 2) an advanced log - a new enhanced log that shows the full traceback from the simulation. This enhanced log is intended to help with debugging simulations and is only available for new simulations run the after v1.26 release.

  • New feature: For block and zone models added new options to adjustments for 1) job spaces and job spaces by building type; and 2) non residential space and non residential space by building type. These new options can be used for simulations that use supporting base data.

  • Zone model: Querying development project attributes on the map with metric unit fields now correctly display field names with their corresponding metric unit label.

  • Fixed an issue affecting a subset of accounts where an unused tag category had the same ID as one used for adjustment tags. This issue would result in corrupting adjustment tags in scenarios.

  • Fixed an issue with the rendering of cells in the uploads and simulation run tables where new upload or run table records would sometimes render with information from the record underneath it.

  • Added validation to the quantities symbology number of bins input box to only support integer values.

  • Fixed an issue introduced in v1.23, where searching for a number in tables could not find numbers cast as a string.

  • Optimized the queries in the tag management window. Tags now load significantly faster.

v1.25.0

  • UrbanCanvas now supports the latest version of Altair (>4.1.0) charts that are exported from simulations and preserves backward compatibility for older versions of Altair. This also solves an issue with simulation Python package dependencies where older versions of Altair were not compatible with the latest version of Pandas.

  • Fixed an issue that would occur when editing an existing base data collection without changing any of the files in the collection and the collection would be be sent to validation when it should not have.

v1.24.1

  • Fixed an issue that some users may have experienced where another layer’s attributes would show up when you query your parcel base data layer while in the base data viewer.

v1.24.0

  • New feature - Quantities layer symbology:

    • Renamed Choropleth symbology to Quantities

    • Any uploaded point, line, or polygon shapefile with numeric type columns can be symbolized on the map using the Quantities symbology option. Prior this, only indicator layers were supported.

    • New option to classify continuous data values into n number of bins. Prior this continuous value classification was limited to only 9 bins.

    • If a column has all Null values, it will not be listed in the field dropdown list.

    • Negative values are now supported in the quantities symbology.

  • New feature - Categorical layer symbology:

    • Any uploaded point, line, or polygon shapefile with numeric and non-numeric type columns can be symbolized on the map using the Categories symbology option. Options are available to add or remove categories for display and change the symbology of all or individual categories. Prior this, symbolizing layer values as categories was not supported.

  • New feature - 3D layer extrusions:

    • Any uploaded polygon shapefile with numeric type columns can be extruded in 3D on the map. Prior to this, only indicator layers supported extrusions.

    • Extrusion height can now be modified using a user specified extrusion factor. The values of the extruded column will be multiplied by the factor and extrusion will be scaled. Prior this, the extrusion factor was limited to a value of 1.

    • When extrusion is turned on: You have the option to turn on or off the base polygons for that extruded polygon and turn on and off the outline and change the outline opacity of the base polygon. When turned on you can query the values of the extruded polygon.

  • New feature - Viewing indicators with simple symbology:

    • Indicator layers can now be symbolized using the simple symbology option and map layer queries for indicators using simple symbology show you the attributes of all columns in the indicator layer for each time point in the time series.

  • New feature - Reverse color scale:

    • Map symbology color ramp scales can now be reversed.

  • New feature - Edit symbology of the OSM buildings layer:

    • You may now customize the default OSM buildings layer extrusion factor, fill color and opacity, outline color, width, and opacity.

  • New feature - Support of discrete time series of indicators:

    • Indicators are no longer required to be a continuous time series. Model results can now be exported to UrbanCanvas that have a discrete number of years available (e.g. Total jobs in years 2010, 2020, 2030, 2040).

  • Fixed an issue where if you had used a search term to filter the available layers list, the search term would still be present when you opened the layer list again. The search bar now clears correctly after the layer has been added to map.

  • Miscellaneous updates to the add and edit layer form:

    • Added a vertical scroll bar in the add and edit layer symbology form.

    • Symbology changes are now only applied to the layer after you complete the layer symbology wizard. Prior to this, your changes were made live as you changed settings in the wizard.

    • Fixed an issue that would sometimes not allow you to select a color from the color picker pop-up when changing the color of outlines.

    • Added a close button to the add and edit layer symbology form that cancels any changes made.

    • Removed the transparent black background behind the layer symbology form when adding or editing a layer.

  • Fixed an issue that was not correctly resetting the subscription simulation run counter on the subscription anniversary date. Now simulation runs correctly reset to 0 upon your subscription anniversary date.

  • Uploaded shapefiles are now capped at a maximum of 1 million vertices for a single polygon. This reduces issues that could occur due to server memory utilization.

  • Fixed an issue where all the years of an indicator would use the same distribution to compute the thresholds used in generating the bins for continuous data symbology. Each year of an indicator now uses its own distribution. This change is only applied to new indicators generated after the v1.24.0 release.

  • Fixed an issue that occurred when deleting a collection with the same parcel geometry file specified as the base data initialization collection would result in removing the layer used for the base data parcel geometry on the map.

  • Updated the external indicator endpoint added in v1.23.0 to accept additional parameters to rename incoming fields for display in UrbanCanvas and enhanced the endpoint’s existing data validation.

  • When querying indicator layers of the same geography level, the attributes of all visible layers queried are shown in the attribute side panel instead of only the top visible layer.

v1.23.0

  • Fixed an issue that could occur with zone model zone layers not displaying correctly on the map and in a select polygon session. This occurred when both the zonal geometry and attribute tables had the same column names.

  • Fixed an issue that was sometimes not allowing the base map to change.

  • New feature: Uploaded graph travel model networks can now be specified for use in a UrbanSim scenario for specific years. This is identical to how skims are specified. Scenario form and table have been updated to reflect the new option.

  • Block model: Constraints form now allows density values to be float.

  • Fixed an issue with block model zoning to constraints conversion tool that would allow the process to begin when no tag was specified when running the tool. If no tag was specified an error would occur during processing. The form for the tool now requires a tag be set prior to running the operation.

  • Optimized constraint and adjustment records to better handle large numbers of records. Speed of loading records on the map and in the table has significantly improved.

  • Adjustments: The filter syntax used in an adjustment record are now displayed in the attribute side panel when querying adjustment records on the map.

  • New feature: New external UrbanCanvas endpoint available to UrbanCanvas Modeler users to upload indicator layers in UrbanCanvas on the fly using Python.

v1.22.2

  • Optimized development project report generation resulting in significant improvement in speed. This solves issues some users may have encountered with large numbers of development projects and large summary geography layers that were hitting a timeout while reports were in progress.

v1.22.1

  • Fixed an issue affecting some users that was causing development project reports that used summary geographies to fail.

v1.22.0

  • Map layers:

    • Added new map layer mouse hover over feature and selection feature for points and lines. Points and lines can now be interacted with on the map in the same manner as polygons.

    • Significantly improved the usability and feedback provided when highlighting and clicking on polygon, line, and point map layers to view attributes especially when features are clustered in close proximity to each other.

    • Standardized the map layer mouse hover over feature and selection feature color scheme across all data types: polygon, line, and point.

    • Added a new map symbology option for polygons and lines to show or hide the vertices of each geometry. This aids in the interpretation of network line layers on the map.

  • Fixed an issue introduced in v1.21.0 that was not displaying the data type on new uploaded files in the uploads page.

  • Major refactor of the block model zoning to constraints conversion tool to optimize it for conversion of large spatial extent zoning data to constraints. Refactor has significantly improved run time and reliability of the tool.

v1.21.0

  • The transmission of logs from the simulation to UrbanCanvas has been optimized to reduce resource usage and increase the speed of transmission.

  • Fixed an issue that would occur when running a block model simulation that was reading development projects from a parcel model account.

  • Fixed an issue that sometimes displayed an error message that a file was not found when deleting uploaded files.

  • Uploaded polygon shapefiles that are found to have invalid polygons are now corrected upon upload. Prior to this change, any polygons that were invalid were not available to be shown in the map resulting in visual gaps in map layer.

  • Fixed an issue with CSV uploads where the status would be stuck on uploading data.

  • Fixed an issue that was causing uploads of geography type network data to fail.

  • Fixed an issue that would cause shapefile uploads to fail if any column names that are used internally to UrbanCanvas were found in the uploaded data. Now those columns are bypassed and the file is allowed to be uploaded.

  • Added a check and message prompt when an uploaded parcel file that is also set as the base data geometry is deleted. Uploaded parcel geometries that are currently set as the base data geometry in UrbanCanvas are not unable to be deleted until a new parcel geometry file is set as the base data geometry.

  • Fixed an issue that would cause the block model zoning to constraints conversion tool to fail when the spatial reference system of either the uploaded zoning data or base data geography were unknown or not the same.

  • Optimized the location on the screen that the runs form opens to for different screen resolutions and sizes.

  • Updated the upload validation service to be more flexible in the segmentation and subregional ID data schema of control total files. Any data schema issues found will now be optional warnings.

v1.20.0

  • Added new feature to configure any map layer to always be turned on with a specific symbology and to show up in the layers panel upon login. If you have layers you would like this configured for please contact us here to have this feature enabled for your subscription.

  • Fixed an issue for zone model bulk development projects uploads that was not auto-generating the area of the project in metric units.

  • Fixed an issue that was causing parcel base data collections to fail the data schema validation when the collection contained a parcel attribute table with no subregional ID column and contained an area per job table with a subregional ID column.

v1.19.0

  • Optimized the location on the screen that the constraint and adjustment form opens to for different screen resolutions and sizes.

  • Fixed an issue that was sometimes displaying tags that were not currently in use as being in use which was preventing their deletion.

  • Fixed an issue with parcel models using adjustments: the adjustment records sent to the simulation were missing the non-residential square footage field.

  • Removed the 255 character limit on all note fields in the user interface, an unlimited number of characters are now allowed.

  • Fixed an issue the data schema validation of control totals that was not correctly validating values found in segmentation columns and also expanded the types of segmentation columns accepted in the default data schema.

  • Added the data schema of subregional control totals to the upload validation service.

v1.18.0

  • Optimized for speed the base data intersection of TAZ or summary geography polygons resulting in significantly improved run time and performance.

  • TAZ and Summary geography intersection now uses a percent area overlap to assign intersecting zone ID to base data geometry instead of the base data polygon centroid intersection with TAZs.

  • In cases where a base data polygon overlaps multiple TAZ or summary geography polygons, the polygon that has the greatest area overlap is assigned the base data ID.

  • Fixed an issue some accounts were experiencing when uploading TAZs due to a mismatch in the data type of the intersecting parcel, block, or zone ID column in the base data.

  • Fixed an issue that would sometimes occur when bulk uploading constraints that were invalid multipolygons.

  • Fixed an issue that was closing the scenario form in the lower right hand side of the screen introduced in v1.17.0.

v1.17.0

  • Updates to the TAZ uploader:

    • TAZ uploads now show a new status to indicate the percent of base data polygons that the TAZ polygons intersected. This provides more information to better understand how comprehensive the overlap is in the resulting base data ID to TAZ ID lookup tables.

    • TAZ uploads that do not intersect any base data polygons are no longer available for use in scenarios and are clearly indicated in the TAZ upload status.

    • TAZ uploads for zone model are now enabled and work as intended.

    • Base data polygons that do not intersect any TAZ polygon centroids are now assigned the TAZ ID of any intersecting TAZ polygon. This solves issues that would occur primarily on the edges of a region’s base data where base data polygons extended well beyond the TAZ boundaries with only a small area of polygon overlap.

  • Updates to base data collections:

    • The restriction on changing the parcel geometry file set in existing base data collections has been removed.

    • The base data shapefile used in the model initialization collection is now allowed to be changed by the user as long as no development projects, constraints, or adjustments exist in the account. If these data exist in your account and you would like to change your base data geometry used in the platform please contact us here for assistance.

    • Summary geography and TAZ polygon intersections with base data geometries are re-run when the base data shapefile used in the model initialization collection is changed to keep all lookup tables up to date.

  • Constraints:

    • Fixed an issue that was displaying 0 values for null or blank values in constraints in the UI. Values stored in the database were correct. If the value is null no value will be displayed.

    • Block model:

      • Renamed constraint columns in the constraint table to reflect the correct units by renaming Employment Capacity to Max employment density and Residential Capacity ` to `Max residential density. Propagated this change to the data generated in the database and reports as well as related services.

    • Zone model:

      • Added the constraint Allowed building types field to the constraint table in the UI and to the query attribute side panel.

  • Updates to the scenario form:

    • Minor update to scenario form to remove the scroll bar on baseline scenario toggle option that was introduced in v1.16.0.

    • Updated the logic used to define the screen position of the scenario form to work better on different screen resolutions. On some screen resolutions the scenario form would open up with half of the form hidden underneath the browser window.

  • Fixed an issue that was not allowing some users to use the select by polygon geometry selection tool.

  • Fixed an issue that was displaying all legends for indicator layers that were listed in the layers panel regardless of their visibility state when a user’s persisted layers were loaded between sessions. Now only legends of indicators that have their visibility turned on are persisted between user sessions on the map.

  • Enabled the query of block model default Census block capacity columns to be viewed in the query attribute side panel.

  • Fixed an issue in control total upload validation that was flagging records as duplicates where more than one segmentation column existed in the control total.

  • Added UrbanSim model support for sub-regional control totals. To utilize sub-regional control totals in your model please contact us here and prepare your control totals to include a sub-regional location identifier column that corresponds to a location identifier in the base data tables (e.g. county id).

  • Added support for the UrbanSim model system to access base data h5 files hosted outside of UrbanSim cloud infrastructure. This allows users to quickly bulk update any table inside of the base data h5 file and use it in simulations launched in the UI. To utilize this please contact us here and provide us a permanent URL for which UrbanSim can use to download the data.

  • Fixed an issue that could occur in parcel models when generating a development project report that used a summery geography file and the parcel base data geography data did not have a parcel_id column. The use of parcel_id has been removed from this process.

  • Fixed an issue in uploads that occurred when you edited an existing upload and clicked the delete button inside the edit record form. The delete button now works as intended.

    • Updated data schema for parcel buildings table where the minimum value for the building_id has been changed from 0 to -1 to allow for unplaced buildings, added an optional column for occupancy_restriction, and changed optional rent and price transaction column names from: residential_price_per_sqft, non_residential_price_per_sqft, residential_rent_per_sqft, non_residential_rent_per_sqft to: res_price_per_sqft_[YEAR], non_res_price_per_sqft_[YEAR], res_rent_per_sqft_[YEAR], non_res_rent_per_sqft_[YEAR] to support multi-year transaction data.

    • Updated data schema for parcel households table here valid tenure column values are now restricted to 1 (own) and 2 (rent) and added support for an optional unit_id column to use with the new optional residential units table.

    • Updated data schema for establishments table where the minimum value for the building_id has been changed from 0 to -1 to allow for unplaced buildings.

    • Fixed an issue with base data collection and transportation network upload validation that was not transmitting errors that occurred when reading the raw data from cloud storage to the UI.

    • Added a new data validation check for column name character length to limit names to a maximum of 31 characters. Any length greater than this is not allowed by PostgreSQL. This removes issues that can be encountered while data are inserted into the database.

    • Truncated data validation messages that returned the IDs of invalid records to the UI to a limit of 20 records.

    • Fixed the validation message sent to UI for control totals when there were invalid min and max value columns found.

    • Made minor updates to miscellaneous validation messages for clarity.
