Trails data were created for the Marin Countywide Plan update. Data was compiled from various sources including: Digitized from Marin County's existing trails maps, data from Tomales Bay State Park, data from Bay Trail, data from Marin County Parks and Open Space, data from Marin Municipal Water District, and data from GGNRA.
Accuracy of data may vary. Trails have been rectified when possible to orthophotography and checked for accuracy by David Hansen of Marin County Parks and Open Space. Areas with tree coverage are not orthorectified and will not be as accurate.
***There is still much clean up work to be done on this data.***
