Assembly of Landsat 7 Data for Coral Reef Mapping

The first challenge for global coral reef mapping with Landsat 7 is in getting global data that is not obscured by cloud cover. Global data acquisition for coral reef mapping was initiated through the Landsat 7 Long Term Acquisition Plan (Gasch et al. 2000). Once the instrument began acquiring data over coral reefs, it took several years to get the needed acquisitions because of tropical cloud cover, and to find ways to purchase or trade for the over 1000 scenes necessary to complete the global coverage. The data assembly was led by scientists in the Institute for Marine Remote Sensing at the University of South Florida. A number of groups within NASA provided Landsat scenes, and collaborators in mapping projects around the world shared their data in order to assemble the most complete possible archive of Landsat 7 data. The archive and online data interface has been developed by the SeaWiFS Project at Goddard Spaceflight Center.
