The U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center Topographic Science team has developed a Web site that provides a wealth of data about topographic change across the United States. The USGS National Inventory of Significant Topographic Changes is available at http://topochange.cr.usgs.gov. The inventory is based on seamless multitemporal elevation data and land cover data. The need for more comprehensive information on the nature and extent of recent human geomorphic activity led to a spatial emphasis for the first ever accounting of topographic change across the United States.

Explore critical pre- and post-disaster images and datasets online for immediate viewing and downloading. The U.S. Geological Survey (USGS) Emergency Operations, in support of the Department of Homeland Security, provides these images for use in disaster preparations, rescue and relief operations, damage assessments, and reconstruction efforts. We supply satellite and aerial images for analysis of disaster areas before, during, and after a disaster.

October 1, 2008 – All Landsat 7 ETM+ scenes held in the USGS EROS archive are now available at no charge. Newly acquired Landsat 7 ETM+ SLC-off images with less than 20 percent cloud cover are automatically processed and made available for immediate download, while all remaining Landsat 7 ETM+ scenes can be processed upon request. Once the requested scenes are processed, an email notification is sent to the customer with instructions for downloading. These scenes will then become accessible to all users.
Landsat 7 ETM+ data can be searched, downloaded, or requested from EarthExplorer (http://earthexplorer.usgs.gov) or Glovis (http://glovis.usgs.gov).
