Online_Linkage: \\DEP-EIA1TSGIS01\images\landcover\maine_gap Description: Abstract: Vegetation and land cover types were derived from 1991 and 1993 Landsat Thematic Mapper imagery. Supervised and unsupervised classification techniques were used to classify nine full or partial scenes. Training samples were derived from interpreted aerial videography flown during 1994. Ancillary GIS data layers used included US FWS National Wetlands Inventory digital and paper maps, USGS Digital Line Graphs, USGS Land Use/Land Cover database, and point locations of blueberry fields and hay fields. Purpose: To serve as input into the Maine Gap Analysis Project. Conservation efforts have concentrated upon rescuing species from the brink of extinction. These programs were reactionary, usually expensive, and sometimes disruptive. In the mid-1980s, the gap analysis method was propsed and tested, to address conservation of all species, not just those currently rare. The gap analysis process provides an overview of the distribution and conservation status of several components of biodiversity. In Maine, specific components of biodiversity include amphibians, reptiles, birds, mammals, and woody plants. The spatial habitat map this document describes was overlaid upon conservation areas, for example (Krohn et al. 1998) to quantify its conservation status and species-rich areas. Gap Analysis, by focusing on all species, is likely to be both cheaper and more likely to succeed than conservation programs focused upon single species or populations.

Source_Used_Citation_Abbreviation: C:\DOCUME~1\sde\LOCALS~1\Temp\17\xml1A.tmp Spatial_Data_Organization_Information: Indirect_Spatial_Reference: Landsat Thematic Mapper scenes were georectified to match positions with high resolution 1:24,000 scale USGS quadrangles. Other significant layers used were: a digital elevation model, supplied by the Maine Office of GIS, which stores metadata for the layer (http://apollo.ogis.state.me.us/); 1:100,000 scale hydrography and transportation layers, documented by USGS; and USFWS National Wetlands Inventory data, which is registered to USGS 1:24,000 scale quadrangles. Habitat patches are most important in determining the horizontal position of potential habitat. These patches were based upon Landsat Thematic Mapper data that was registered to 1:24,000 scale control points. The patches were identified as homogeneous habitat using a mixed supervised/ unsupervised classification (see Hepinstall et al. 1998) and aerial videography images. Vegetation patterns in Maine were sufficiently fine to allow us to identify the exact location of aerial videography frames relative to the Landsat imagery.
