AB: The U.S. Geological Survey (USGS) AmericaView program was created to advance the availability, timely distribution, and widespread use of land remote sensing data, especially in the university community. One of the obstacles that researchers encountered in the past was the difficulty of identifying and acquiring the most appropriate data for their particular application and study area. The AmericaView program funded the development of the Global Visualization (GloVis) Viewer to overcome this barrier. GloVis provides a browse image-based search capability for mining the data inventories held at the USGS Earth Resources Observation Systems (EROS) Data Center. The holdings include land remote sensing data from the Landsat, Earth Observing-1 (EO-1), Terra, and Aqua satellites. GloVis is updated daily with browse images and metadata. A global locator map is used to navigate through a mosaic of browse images that are available for the selected sensor and acquisition period. Users can readily view current or historical browse images at global or regional scales, or zoom in and view single images. The ability to visually browse image content and extent enables interested users to geographically and temporally scroll through the image archives. GloVis fulfilled the goal of providing a visual data selection tool that allows a user to quickly and accurately be able to locate and order the optimum data for their research needs. In addition, the software code for the system is freely available, and other organizations have adapted it to create similar visual web-based tools to access their own remote sensing data archives.
