NASA satellite images regularly map active fires around the world. Once a fire is out, satellite data and maps are also used by scientists to measure and protect the scorched land, and have played an important role in streamlining fire recovery efforts. The Remote Sensing Applications Center (RSAC), operated by the U.S. Department of Agriculture
