Land cover rasters (raw data) - Selawik National Wildlife Refuge

This geodatabase contains three (3) rasters, two (2) of which represent landcover for Selawik National Wildlife Refuge and surrounding areas. The third raster contains plot-based ground characteristics for pixels classified with high confidence. The two landcover rasters contain attribute information for soils, vegetation, and ecotypes; and differ slightly in their classifications because one encompasses a broader geographic area (lc_arcn), and therefore some classes are more generalized than in the other (lc_nokose).

The classification of local-scale ecosystems (ecotypes) combines physiography (e.g., riverine, coastal), topography (DEM), geology and vegetation from the landcover spectral database derived from the satellite image processing. These layers are used to model ecotypes in a way that best partitions geomorphic, hydrologic, pedologic, and vegetative characteristics.

Map projection: Albers Alaska, NAD 83, meters.

NOTE The lc_nokose raster was used for the landcover classifications in the final report, as it is more specific to Selawik National Wildlife Refuge than the other landcover raster (lc_arcn), which includes some surrounding National Park Service lands and differs slightly in its classifications at the pixel level.

PDF maps are provided here for reference to help visualize what the data look like before downloading. Full resolution maps can be viewed in the final report (ServCat #49603).
