Abstract: Geologic Map of the Monterey 1:100,000 Scale Quadrangle and Monterey Bay: A Digital Database

A new geologic map of the Monterey 1:100,000 scale quadrangle and Monterey Bay has been compiled by the California Division of Mines and Geology and Moss Landing Marine Laboratory. The map 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 cooperative mapping program, STATEMAP.

On shore, 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 The map was updated where new mapping was available.

Offshore, a wealth of new geologic information was available. These new data were overlain on new high resolution baththymetry acquired by the Monterey Bay Research Institute.
