Abstract



TerraLook: A GIS-Ready Time-Series of Satellite Imagery
Track: Remote Sensing Imagery
Author(s): Eugene Fosnight, Claudia Young, Gary Geller

TerraLook aims to provide satellite images that anyone can use to see changes in the Earth's surface over time. Landsat and other satellite sensors have been collecting Earth images for more than 30 years. TerraLook allows users to create their own collections of georeferenced, simulated natural-color JPEG images from Landsat (circa 1975, 1990 and 2000) and ASTER (2000 to present) at no charge. The simulated natural colors in TerraLook images are consistently processed so that images from four time periods can be easily compared. TerraLook images are bundled with standards-compliant metadata, a world file, and an outline of each image's ground footprint, enabling their use in Geographic Information Systems and Web mapping applications. For ArcGIS, ArcExplorer and ArcGIS Explorer users, project files are available, which allow users to easily integrate TerraLook collections into GIS projects or educational curricula for visual analysis.
