Feb 10, 2008 • USGS and NASA researchers teamed together in a highly ambitious effort to reconstruct historical land cover and biophysical parameters of the eastern U.S. Their resulting data sets will support future climate modeling, studies concerning the impact of historical land cover change on water, energy and carbon budgets (and cycles), as well as ecosystem dynamics research. Louis Steyaert and Robert Knox reconstructed maps of land cover and various biophysical parameters for the eastern U.S. circa 1650, 1850, 1920 and 1992 (at 20-km resolution). Their reconstruction relied on a wealth of inputs from census data, soil data, published historical land use information, and land cover classification information derived from Landsat data (National Land Cover Data 1992).
