creation_method Contains the current range polygons as contained in the ECOS database; no generalization was performed and no data was intentionally omitted. Polygons are created by field staff utilizing the ECOS system to select range per office. The office datasets are then dissolved into one species range file and simplified using the Douglas-Peucker algorithm with a 0.0001 tolerance. The polygons were then transformed to a binary 30m raster layer. The polygons were then transformed to a binary 30m raster layer, where 1 represents potential habitat.
