Title: "World at Night" (2006) Description: World at Night represents a nighttime view of the Earth produced by mosaicking Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) satellite images. This system was originally designed to view clouds by moonlight and to map the locations of permanent lights on the Earth's surface. These data are derived from 9 months of observations superimposed on a darkened land surface. ESRI georeferenced these data to a real world coordinate system. World at Night provides an informational and educational view of our planet at night. | ||||
