We provide a more comprehensive methodology for the Parcel Canvas features, click here to view or download the Parcel Canvas Technical Guide.
Using the Create Project feature, you can choose to create parcel-based projects across the US. The UrbanFootprint parcel-based canvas is built using information sourced through our strategic relationship with CoreLogic, a leading provider of real estate data in the United States, as well as a number of other data sources and methods used to normalize, clean, and curate a comprehensive parcel land use base. UrbanFootprint’s coverage includes access to over 112 million parcels, which covers almost every county in the United States with populations over 45,000 people, as of March 2019.
The parcel canvas data features:
- Dwelling units and building area. This data is either obtained directly from city data and county assessors’ data or, if not available, imputed by an UrbanFootprint process that extrapolates unit counts and building volume from land use information.
- Household and population data calculated from census rates.
- Employee counts disaggregated from census LEHD data using land use to filter employees and building volume to eligible parcels.
- Building Type designations and data assigned via land use codes.
When creating projects, you will have the option to choose between using a parcel- or census block-based project canvas. While census block-based canvases are relevant for larger-scale work, a parcel-scale canvas will provide the detail required for city, corridor, neighborhood, and site-scale planning and urban design work.
Using a parcel-scale project will enable you to:
- Access the higher quality data that comes directly from local assessors who provide more contextual understanding.
- Visualize more detailed information made available at the parcel level.
- Create, filter and/or upload polygon boundaries for custom project areas with more precision based on parcels.

Notes on Creating and Working With Parcel-Scale Projects
Here are a few considerations to keep in mind:
- Since there are usually more parcels than blocks for a given project area, it will take slightly longer for UrbanFootprint to build a parcel canvas compared to a block canvas.
- Similarly, running analytics on parcel-scale projects will take longer than running them on a block scale project.
- The maximum size of a parcel-based canvas is 250,000 parcels. This will cover the vast majority of cities and many counties. If you have specific needs for a larger canvas, please contact us.
- For some counties you will be able access parcel geometries and data for use within UrbanFootprint but you will not be able to download the parcel canvases.
UrbanFootprint has two types of canvases, Census Block-based and Parcel-based. The Census Block Canvas is available across the entire U.S. for every state. The geometries of the canvas are the same as the census blocks in the project area.
The Parcel-based Canvas' coverage is limited to counties in the United States with populations of 45,000+ residents.
Below is a map of our current Parcel canvas coverage map. With our current dataset, UrbanFootprint’s parcel coverage encompasses more than 85% of the US population!
Canvas Export Restrictions
There are some counties whose canvases that UrbanFootprint cannot export due to licensing restrictions. We're constantly working with our data partners to make this information available for export in the future. They are located below:
The following 6 counties have populations larger than 45,000 and do not have a parcel-base canvas: Whiteside, IL; Pike, KY; Lafourche, LA; St. Landry, LA; Vermilion, LA; and Berrien, MI.
If you don't see your Project/Study area in the Parcel Coverage map, there's no need to worry!
If your area is located in a county we do not currently have coverage for, contact your Customer Success team member at Ask@urbanfootprint.com to discuss data availability and acquisition.
