The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) has created high-resolution land cover/use data sets for the Upper Mississippi River System (UMRS) from 1:15,000-scale color infrared aerial photos collected in 1989. The data are available in two formats. The first used a detailed genus-level classification scheme and was used to classify Mississippi River Navigation Pools 4 through 26, the Open River between Grand Tower and River Mile 32, and the Peoria navigation Pool on the Illinois River. The second classification scheme was developed in 1998 in response to a scientific and programmatic review of the center's mapping projects. This classification scheme identifies plant communities...
The objective of this project was to produce an Alaskan Existing Vegetation Type (AKEVT) map at 30m resolution for a portion of the Western Alaska Landscape Conservation Cooperative (WALCC) region using a very consistent (2000 +/- 1 yr.) remote sensing data set (Landsat 7 ETM+) and the same methodology. The mapped area encompasses the western and northern parts of the WALCC region, plus the Kodiak Archipelago.
