SURVEY PRODUCTS


The images here are representations of the DEM map products created from the processed bathymetry data. The respective digital data files are available for download from the Data Downloads page. The file descriptions are listed as a 10-m cell size bathymetry grid and the file format is a Esri 32-bit floating point grid. Each survey area is available in two datums: (1) ITRF00 equivalent to WGS84 G1150 and ellipsoid height, and (2) NAD83 and NAVD88 orthometric height with respect to GEOID12A.

Bathymetry - Ellipsoid Height - ITRF00 (WGS84 G1150)

   

Bathymetry - Orthometric Height - NAVD88
