TerraLook: Satellite Imagery to View a Changing World

TerraLook provides both ASTER and Landsat data as simulated natural-color JPEG images. TerraLook aims to serve user communities who have a need for images of the Earth but do not have technical remote sensing expertise or access to expensive and specialized scientific image processing software. TerraLook Collections consist of readily usable remotely sensed images designed for visual interpretation and are distributed at no cost to the user. TerraLook collections will be of value to anyone who wants to see the changes to Earth’s surface since 1972. The georeferenced TerraLook product is compatible with most GIS and web mapping applications.

Millennium Coral Reefs Landsat Archive

The Landsat 7 satellite data acquisition strategy facilitated the first complete cloud-free coverage of the world's coral reefs. Landsat data for a number of these coral reef scenes were assembled by the University of South Florida and NASA's Johnson Space Center and are available from the Millennium Coral Reefs Landsat Archive.

Multi-Resolution Land Characteristics Consortium (MRLC)

MRLC is a group of federal agencies who joined together to purchase Landsat 5 imagery for the conterminous U.S. and to develop a land cover dataset called the National Land Cover Dataset. In 1999, a second-generation MRLC consortium was formed to purchase three dates of Landsat 7 imagery for the entire United States and to coordinate the production of a comprehensive land cover database for the nation called the National Land Cover Database. The MRLC consortium is specifically designed to meet the current needs of Federal agencies for nationally consistent satellite remote sensing and land-cover data. However, the consortium also provides imagery and land cover data as public domain information. The MRLC data are in Albers Equal Area projection and cost $45 per scene.
