Base Canvas Attributes

Understand the attributes of the Base Canvas.

The Base Canvas includes attributes that describe land use, demographics, and development for each parcel or census block feature. UrbanFootprint's Base Canvas loading process incorporates a number of data sources to populate the attribute columns, including population and housing data from the decennial census and American Community Survey; employment data from the Longitudinal Employer-Household Dynamics (LEHD) program; and parcel data provided by CoreLogic. (UrbanFootprint can also incorporate local parcel data to create custom parcel-scale canvases.) Detailed information about the process to generate the Base Canvas at the parcel and block resolutions can be found in the Parcel Canvas Creation Methodology and Block Canvas Creation Methodology.
