Satellite maps shows explosion in paved surfaces in D.C. region since 1984

It’s no secret the D.C. area has witnessed a development boom since 1984. But to see it from the vantage point of space is eye-opening.

University of Maryland researchers recently published satellite-based maps showing the extent of impervious surfaces in both 1984 and 2010.  Impervious surfaces are those that water cannot penetrate, like roofs and roads.
