LiDAR data and orthophotography were provided by the University of Maryland under grant  NNX13AP69G from NASA's Carbon Monitoring System (Dr. Ralph Dubayah and Dr. George Hurtt, Principal Investigators). This grant also funded the creation of derived forest cover and land cover information, including a countywide biomass and carbon map, a canopy cover map, and DEMs. The Sonoma County Vegetation Mapping and LiDAR Program funded LiDAR derived products in the California State Plane Coordinate System, such as DEMs, hillshades, building footprints, 1-foot contours, and other derived layers.  The entirety of this data is freely licensed for unrestricted public use, unless otherwise noted.  Any use of these data, including value-added products, within reports, papers, and presentations must acknowledge NASA Grant NNX13AP69G, the University of Maryland, and the Sonoma Vegetation Mapping and LiDAR Program as their sources.
