Name: Bathymetry - San Antonio Bay

Display Field:

Type: Raster Layer

Geometry Type: null

Description: Bathymetry for San Antonio Bay was derived from five surveys containing 32,829 soundings. Two older, overlapping, less accurate surveys were deleted before tinning. The average separation between soundings was 134 meters. The five surveys used dated from 1934 and 1935. The range of soundings was 0.2 meters to -12.2 meters at mean low water. Mean high water values between 0.2 and 0.4 meters were assigned to the shoreline. No points were edited out of the data set. San Antonio Bay has twelve 7.5 minute DEMs and a single one degree DEM.
