DOC Maps

Geospatial Data and Web Maps from the California Department of Conservation.

The Department of Conservation provides services and information that promote environmental health, economic vitality, informed land-use decisions, and sound management of our state’s natural resources. As home to the California Geological Survey, the Division of Oil, Gas, and Geothermal Resources, Division of Land Resource Protection, and Division of Mine Reclamation, spatial data informs virtually every aspect of the Department’s activities.

The California Department of Conservation (DOC) is a prolific producer of spatial data and manages much of the data using Geographic Information Systems (GIS).
