Detecting Landcover Change
The Center for Earth and Planetary Studies has an extensive archive of Landsat Thematic Mapper (TM) data. We are exploring methods of using these data for detecting landcover change in the Washingotn area. The objective is to identify simple methods for locating large areas undergoing change from unpaved to paved landcover.
Several large projects are visible in the images: the Dulles Greenway and development around Ashburn, VA, a new football stadium in Maryland, and construction of the Metro green line in Prince George's County and southeast D.C.
These are preliminary results. Accuracy assessments have not been performed and the results have not been subject to scientific peer review. Stay tuned for future developments.
