Bathymetry in fathoms for Massachusetts and adjacent coastal waters (as polygons)
Entry ID:
CZM_moris_bathy_fathoms_poly
Summary
Abstract:
These GIS data represent a mosaic bathymetric datasets off waters of the coast of Massachusetts derived from the most current and accurate sources. Data sources include USGS Open File Reports, NOAA Estuarine Bathymetry, and the NOAA Coastal Relief Model. Since these sources vary in spatial resolution from 2m to 90m, 30m was selected to represent a median spatial resolution for mosaicking. The raster mosaic was then
Purpose: These data were developed to form a continuous bathymetry for all Massachusetts state and adjacent waters.

ATTRIBUTE ACCURACY REPORT: n/a
LOGICAL CONSISTENCY REPORT: The mosaicked data set were checked for bad values (errant soundings) and "ledges" between adjacent data sets representing potential datum conflicts. The data appear to be free from bad values and edgematch well. COMPLETENESS REPORT: The data contain bathymetric polygons for the entire geographic extent. There are no known omissions. ...
