A new geologic map of the Monterey 1:100,000 scale quadrangle and Monterey Bay was completed by the California Division of Mines and Geology and Moss Landing Marine Laboratories. Themap is a digital database which, for the most part, was digitized at 1:24,000 scale using ALACARTE, a menu-driven module developed by the U.S. Geological Survey running on Arc/Info GIS software. This project was supported in part by the U.S. Geological Survey through its National Cooperative Geologic Mapping program, STATEMAP component. Onshore, existing geologic maps, mostly at 1:24,000 scale were digitized and tiled together to make up the 1:100,000 scale map. An earlier analog version of the map was used as a guide to correct boundary problems between quadrangles. A DEM with 30 meter resolution was used for a shaded relief basemap. Offshore, a wealth of new geologic information was available. These new data were overlain on new high resolution bathymetry acquired by the Monterey Bay Research Institute and the U.S. Geological Survey. The bathymetry was converted to a shaded bathymetric base map.
