Global Land Cover Test SitesEntry ID: glcts
Abstract: The Global Land Cover Test Sites (GLCTS) project is a component of the National Aeronautics and Space Administration's Landsat Pathfinder Program. Pathfinder projects focus on the application of existing remote sensing data collections to issues of global change and focus on the exploration of data management issues, which will be encountered in the Earth Observing System Data and Information ... System (EOSDIS) environment. The targeted user community includes researchers developing regional- and global-scale land cover assessments, researchers developing improved algorithms for land surface parameterization, and field scientists at the test sites exploring the uses of remote sensing.
The primary component of the GLCTS data set is Landsat data, both multispectral scanner data and Landsat thematic mapper data. In addition, a series of daily Advanced Very High Resolution Radiometer 1-km data acquisitions, digital elevation model data (i.e., in some instances, digital terrain elevation data), and land cover information is included for the sites.

Quality The selected test sites represent a wide range of global land cover types, are well characterized on the ground, and have ongoing field-based monitoring programs. The scenes have been screened for cloud cover and band quality, resulting in a high grade, high quality data compilation.
Access Constraints Some Landsat thematic mapper data may be available only to members of the U.S.
Government and its Affiliated Users. Some digital terrain elevation data may be
restricted to use only by nonprofit organizations.
Use Constraints There is no guarantee of warranty concerning the accuracy of these data. Users should be aware that temporal changes may have occurred since the data was collected and that some parts of these data may no longer represent actual surface conditions. Users should not use these data for critical applications without a full awareness of their limitations. Acknowledgement of the originating agencies would be appreciated in products derived from these data. Any user who modifies the data set is obligated to describe the types of modifications they perform. User specifically agrees not to misrepresent the data set, nor to imply that changes made were approved or endorsed by the U.S. Geological Survey.
