Dr. Dale Quattrochi, one of the lead scientists on the urban heat island study, was recognized as a world leader in the field of thermal infrared remote sensing by the Association of American Geographers' Remote Sensing Specialty Group. Quattrochi received the group's Outstanding Contributions Medal for 1999 at the group's annual convention in Hawaii. Quattrochi is one of only two NASA or non-academic researchers to receive the award since its inception in 1980. Quattrochi earned a doctorate in geography from the University of Utah in Salt Lake City, a master's degree from the University of Tennessee in Knoxville and a bachelor's degree from Ohio University in Athens. Aircraft are also needed to provide images to show heat storage the night immediately after a daytime observation since Landsat's orbit does not provide that sort of coverage.
Red dots show the urbanization of Atlanta and environs in a period of almost two decades.
The images are derived from the Landsat Multispectral Scanners. Landsat imagery helps scientists track city growth in urban heat island studies. NASA and University of Georgia Landsat 7 will also help scientists look into the past so we can chart the future better. What is known is that at the time of their collapse the Maya had cut down most of their trees. NASA Earth Science Enterprise captures the spirit of exploration and focuses it on our own plan The Landsat home page includes information on the mission and the satellite.
