Soils EXTENT: San Diego region (except Anza-Borrego Desert and Cuyamaca Rancho State Parks) DATE OF DATA: Early 1970's
Anza-Borrego Desert & Cuyamaca Rancho State Parks are not mapped as part of the original soil survey. This data was digitized directly off the paper soil series maps by San Diego State University, Department of Geography. No attempt was made to rectify the soil polygon boundaries to an accurate photo basemap.
