ResourcesIdentification of Important Habitats in Coastal New HampshireGIS Raster Files Produced from the Great Bay Habitat Mapping Pilot ProjectWetland digital data may be obtained directly from the National Wetland Inventory. The Great Bay report is available (excluding graphics) in Word Perfect (Version 5.1/5.2) in a zipped file format. <download text > The following digital data are in a band interleaved by line (.bil) raster format and may be imported into GIS and viewer software programs once the *.zip files are uncompressed (use PKUNZIP <download PKUNZIP>). The header information enclosed with each compressed file is correctly read by ARCINFO GRID and most versions of ARCVIEW. A metadata text file is enclosed for each raster data set. Habitat quality was indexed on either a 0 - 10 (0 = unsuitable, 10 = optimal habitat) or 0 - 100 (0 = unsuitable, 100 = optimal habitat) scale. To combine habitat quality scores for wildlife species, grids on a 0 - 100 scale were re-classified on a 0 - 10 scale. Using GIS processing, regionally important habitats within the Gulf of Maine were identified by multiplying habitat quality scores (0 - 10 scale) for select species (Table 3) by their respective Gulf of Maine Council rank (indexed on a 1 - 10 scale). Locally important habitats within coastal New Hampshire were identified by multiplying habitat quality scores (0 - 10 scale) for all species (Table 4) by the relative scarcity of habitat for respective life stage (indexed on 1 - 10 scale; 1 = most abundant, 10 = most rare). A vector coverage of coastline is provided as a spatial reference (in ARCINFO export format, zipped)- COASTLIN <zipped .e00 file> ATTRIBUTES OF DIGITAL RASTER DATA: COORDINATE SYSTEM: Projection STATEPLANE Zone 4676 Datum NAD83 Units FEET Spheroid GRS1980 Cell Size = 93.493 Data Type = Integer Mapping of habitat for the various species required the use of three different geographic boundaries to enclose the area of interest. For example, an area enclosing inland tributary streams was required to map habitat for species such as the Atlantic salmon (Boundary A Figure of Geographic Boundaries). A second boundary area was used for bathymetry and other anadromous fishes (Boundary B Figure of Geographic Boundaries). A third boundary area was used for marine fishes (Boundary C Figure of Geographic Boundaries).
