This dataset, which represents county Federal Information Processing System (FIPS) codes for each county as a raster, is utilized by reVX to compute setbacks (distances). Setbacks can be computed either locally (on a per-county basis with specified distances or multipliers) or globally under a generic setback multiplier assumption applied to either the turbine tip height or the base setback distance. A County FIPS code is a five-digit numerical identifier that uniquely identifies counties and county equivalents in the United States The initial two digits represent the FIPS state code, while the final three digits signify the county's unique code within that state. For instance, 55025 corresponds to Dane County, Wisconsin. The first two digits - 55 - represent Wisconsin, and the last three digits - 025 - denote Dane County.
