MarinMap/Marin County GIS Disclaimer

 

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. There are also color aerial orthophotographs from March 31/April 1, 2004 available (“ortho” means that the photographs have “real world” coordinates). 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.
