| Arc ASCII and GeoTiff DEMs of the North-Central California Coast (DEM_#_ASCII and DEM_#_GeoTIFF) |
ATV |
A seamless, 2 meter resolution digital elevation model (DEM) was constructed 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 m elevation contour. |

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. |

| Hydro-flattened Elevation Area Outlines for DEMs of the North-Central California Coast (Hydro_flattened_water.shp) |
ATV |
A GIS polygon shapefile outlining the extent of small lakes or ponds within the terrain that were assigned a
hydo-flattened elevation during lidar post-processing. DEM elevations within these small areas reflect water
surface elevations, not bathymetric elevations. |

| Input Data Boundary Outlines for DEMs of the North-Central California Coast (DEM_source_data.shp) |
ATV |
A GIS polygon shapefile outlining the boundaries of the native input datasets used to construct a seamless, 2-meter resolution digital elevation model (DEM) was constructed 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 m elevation contour. |
