Dataset description: Coverage Polygons for DEMs of the North-Central California Coast (DEM_coverage_areas.shp)
Geometry
A GIS polygon shapefile outlining the extent of the 14 individual DEM sections that comprise the
seamless, 2-meter resolution DEM for the open-coast region of the San Francisco Bay Area
(outside of the Golden Gate Bridge), extending from Half Moon Bay to Bodega Head along the north-central
California coastline. The goal was to integrate the most recent high-resolution bathymetric and topographic
datasets available (for example, Light Detection and Ranging (lidar) topography, multibeam and single-beam
sonar bathymetry) into a seamless surface model extending offshore at least 3 nautical miles and inland
beyond the +20 meter elevation contour.
