Title: Earth Now! Landsat Image Viewer
Url: http://earthnow.usgs.gov/
Publisher: Geological Survey (U.S.)
Description: This viewer lets users see near real-time images from the Landsat 5 Thematic Mapper (TM) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+). When a Landsat satellite passes within range of the ground station at the USGS Center for Earth Resources Observation and Science (EROS), image data are downlinked and displayed in near-real time. When no satellites are within range, the most recent pass is displayed. By viewing the moving display, students can monitor changes in the Earth's surface. An index map and information display shows the path of the satellite, indicates which satellite is currently providing the imagery, and gives the acquisition date and time. A help page and frequently-asked-questions feature are provided to explain how to use the site.
