Aquatic Ecoregions in the United States GIS Data for the EPA Clean Air Mapping and Analysis Program (C-MAP)
Listed in NASA Earthdata CMR
Ecoregions are based on perceived patterns of a combination of causal and integrative factors including land use, land surface form, potential natural vegetation, and soils (Omernik, 1987).
Description
This is a copy of the ecoregion coverage of Omernik (1987) with some item names modified. This coverage is intended for national-level studies of water resources.
Reviews_Applied_to_Data. The Ecoregions were plotted on a terminal to ensure the EXPORT file was imported properly. No claims are made regarding the accuracy of the original data or linework.
