Defense Meteorological Satellite Program's Operational Linescan System,
researchers have been able to look at urban sprawl by monitoring the
emission of light from cities at night. By overlaying these "light maps"
onto other data such as soil and vegetation maps, the research shows
that urbanization can have a variable but measurable impact on
