        Bathymetry information from soundings, NOAA nautical charts, existing coverages, and aerial photo- interpreted sources
for the Gulf of Maine was developed into a raster coverage of bathymetry and intertidal cover types. This was
part of the information used to map potential habitat for fish and wildlife; see gombathydoc.htm Online_Linkage: Larger_Work_Citation: Citation_Information: Originator: Gulf of Maine Program Publication_Date: Title: Gulf of Maine Habitat Mapping Project Publication_Information: Publication_Place: Falmouth, Maine Publisher: U.S. Fish and Wildlife Service, Northeast Region Online_Linkage: Description: Abstract: We used sounding data in deeper areas to generate a relatively coarse resolution bathymetry grid. Finer spatial resolution around inshore features were achieved by use of tidal exposure classifications described from aerial photography (e.g., "regularly flooded, irregularly exposed, irregularly flooded") in the USFWS National Wetland Inventory data sets, and also channels and tidal flats mapped from photography in Maine's Coastal Marine Geologic Environments (CMGE) and Massachusetts orthophoto wetlands maps. These classes were not translated into absolute elevations, but instead were coded as to position within the intertidal zone, and the general cover type (e.g., high marsh, lower intertidal flats, etc.), which may convey useful ecological information. Where nearshore subtidal bathymetry were inadequate, the grid was 'patched' using grids developed from scanned NOAA charts. Purpose: Used as part of the environmental data to identify valuable habitats for conservation and management.

DATA_QUALITY_INFORMATION Attribute_Accuracy: Attribute_Accuracy_Report: The mapped areas were compared to geo-referenced digital NOAA nautical charts as a general check for processing and data errors. Logical_Consistency_Report: Completeness_Report: The coverage may erroneously characterize depths because of limitations of the source data and processing errors from averaging point values. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Data set accuracy generally ranges from that of the 1:24,000 base data (inshore) to the 15 second raster data (used offshore).
