Collection Overview: This dataset is intended for researchers interested in active tectonics and earthquake hazards research in the Central Coast region of California, and the areas north and east of San Francisco Bay. The target areas were developed and defined by USGS scientists in collaboration with colleagues working in these regions. The target areas in the Central Coast region are: the Big Sur area and the Oceanic and San Simeon Faults. The target areas in northern California are: the Bartlett Springs and Berryessa Faults, the Greenville Fault, and the Rodgers Creek Fault - Maacama Fault stepover area. The data collection and processing were purchased by the U.S. Geological Survey using funds provided via the American Recovery and Reinvestment Act of 2009 (ARRA).

Please note that the raster products contain an orthometric elevation, so those elevations are with respect to the NAVD88 vertical datum (EPSG:5703). This is different than the lidar files which are ellipsoidal-referenced elevations and are with respect to the WGS-84 ellipsoid.
