Vector Data
 

The following GIS vector data layers are provided in a shapefile format and compressed into a ZIP file for easy downloading. Corresponding metadata is provided in both HTML and XML formats. To download our 2000 aerial photos please go to the Raster Data page. Questions about these data layers should be directed to gis@sonoma-county.org.

The County of Sonoma Permits and Resource Management Department (PRMD) maintains additional GIS datasets which are available to download from their GIS Data Download page. You can also view the data interactively with the ActiveMap web mapping application.

A Note About Digital Terrain or Contour Data:
The County of Sonoma uses publicly available elevation data available from the National Elevation Dataset (NED) to satisfy its basic elevation mapping requirements. Digital Elevation Model (DEM) and contour information may be downloaded from the United States Geological Survey (USGS) National Map portal. These data meet National Map Accuracy Standards (NMAS) for 1:24,000 scale data, and typically have 10 meter resolution. If your project requires data with a higher resolution, you should contact a private contractor that is capable of producing high resolution data for site-specific needs.
