GIS Downloads

SANDAG and SanGIS have joined forces to provide a single authoritative regional GIS data source.

Regional GIS Data Warehouse

The Regional GIS Data Warehouse provides data for everything from addresses to zoning, including: roads, property, parks, lakes, topography, census, and dozens of other layers - over 270 layers in 29 different categories.

The public facing data are free to download after accepting the data disclaimer which is presented to each user upon entering the Regional GIS Data Warehouse. The data are stored as compressed "Shape" files (SHP). Metadata (information about the data) are provided in PDF format.

A complete list of available layers can be downloaded as an Excel or PDF file.

SANDAG Defined Reporting Areas

SANDAG maintains GIS layers modified to support our forecasting and modeling efforts. Some of the SANDAG defined reporting areas coincide with data reported in the SANDAG Profile Warehouse and Data Warehouse.

Projection/Coordinate System

SANDAG GIS databases use the GRS80 Spheroid, California State Plane Coordinate System (feet), Zone VI, North American Datum 83 (NAD 83).
