Geographic Research

Welcome to the U.S. Geological Survey (USGS) Web page for Geographic Science of Alaska. Geographic Science at the USGS Alaska Science Center involves investigations into the use of remote sensing and GIS technologies for characterizing terrestrial ecosystems and land processes in the boreal and arctic regions of the U.S. Many of these projects directly support the U.S. Geological Survey Global Change Research Program, an operational component of the U.S. Global Change Research Program (USGCRP). The research activities described in this page relate primarily to the USGS theme of Land Surface Characterization and Land Remote Sensing.
