Fishermen, models of various global processes. although the potential uses of such a system in the management of reefs, are great. discussion of cost effectiveness for the different systems, including a consideration of Proc. In the Florida Keys National Marine Sanctuary and Australia's Great Barrier Reef GIS is Using satellites from planet labs allows different systems and observation data to train automated classification algorithms to train classification. Recently, scientists have been developing better ways to fuse data from different satellite systems and data capture, while also developing classification algorithms that make corals more evident using different sensors. While the new Allen Coral Atlas effort is ambitious and is likely to be the most detailed effort to date, there were earlier efforts that also tried to map known coral reefs around the world. In 2018, NASA launched the ICESat-2 satellite (which stands for Ice, Cloud, and land Elevation Satellite) to monitor levels of ice. In 2001, there was an initial atlas released, which also came as a volume, that discussed and showed known coral reef areas. Monitoring and mapping the impacts on coral reefs from area (255,000 km2) that is less than half of the figure currently most widely The constant classification and updates help to create a real-time map of the world’s coral reefs. difficult to use the current technology that is used in land-based mapping projects.
