| Welcome to the GIS data download site. MarinMap and County of Marin have posted a variety of useful GIS data files in ESRI shape format. The files are grouped under common headings for the type of data and listed in Alphabetical order. All GIS data are in California State Plane coordinates, NAD83, HARN in US Survey feet. These files have been compressed into “zip” files to reduce their size for downloading. You will need a free utility such as “WinZip” to “unzip” the files for use.
