Redistricting Data Mapping Files
Redistricting Data Mapping Files
GIS mapping files contain geographical information, which are spatial data encoded into a file format.
Examples include:
- Shapefiles (Partnership, TIGER/Line, Cartographic Boundary)
- KML (Google)
- File Geodatabase (ESRI) files.
We use Partnership Shapefiles in our partner programs to share data with and capture data from our partners.
TIGER/Line Shapefiles do not include demographic data, but they do contain geographic entity codes (GEOIDs) that can be linked to the Census Bureau’s demographic data, available on data.census.gov.
KML is a file format used to display geographic data in a tool such as Google Earth or Google Maps. All cartographic boundary files are available in KML format starting in 2013.
