Geographic Science






Geographic Science of Alaska

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.

This study will conduct an assessment of fire size, frequency, and severity in Alaska using circa 1970-2006 Landsat MSS, TM, and ETM+ satellite data.

Fire regime characteristics in the Alaskan boreal forest and the subsequent impact on successional trajectories are monitored using a combination of remotely sensed and in situ data.

IKONOS imagery, IKONOS-derived shrub canopy density, and preliminary coarse resolution shrub canopy density estimates derived from Landsat and MISR. Alternative Approaches for Remote Sensing of Forest and Shrub Cover in Arctic Tundra and Boreal Forest Environments
The recent completion of the National Land Cover Database product in Alaska allows for a valuable first look at the distribution of broad vegetation types across the state.
