Integrated Land Change Monitoring

Satellite images that have been continuously acquired for many decades represent a unique record of our planet’s surface. At EROS, we analyze satellite and other data to determine not only how the Earth’s land cover has changed over time, but also the driving forces behind the changes. Understanding the how and why of past land cover and land use change makes it possible to more accura

Developing General Coastal Vegetation Maps for Coastal Morphodynamic Models

The USGS is collaborating with researchers from other agencies, academia, and industry to predict coastal impacts from hurricanes. The results from this study will better inform coastal morphological change models, which will lead to improved hurricane impact projections.

Alaska North Slope LiDAR

High-resolution light detection and ranging (lidar) elevation data were acquired along the north coast of Alaska between 2009 and 2012. The lidar acquisition, from Icy Cape, Alaska to the United States/Canadian border, comprised approximately 11,000 km 2 . The airborne lidar data were acquired in support of the U.S. Geological Survey Coastal and Marine Geology Program. The purpose of this lidar...

Ranking Features Based on Magnitude of Change

Each of the polygons in the topographic change inventory has numerous attributes associated with it. These attributes allow a ranking of features based on the magnitude of change, as measured by polygon descriptors (area and volume) and changes in terrain parameters (elevation, relief, slope, aspect). The ability to do such a ranking points out one of the advantages of producing spatially explicit...
