Every week TerraMetrics, in cooperation with the Kansas Applied Remote Sensing Program based at the University of Kansas, produces a set of four vegetation maps using satellite data for the entire United States. The set of maps is called the GreenReport®. The maps, initially developed by the KARS Program as part of its ongoing NASA research, illustrate crop\vegetation progress and condition. Light colored areas in Difference Map 3 illustrate the extreme drought conditions that were present in Texas and Oklahoma during the summer of 1998, where agricultural losses were in the millions of dollars. Dark green areas are those where foliage is more lush than average.
