Modeling Urban Expansion in the Philadelphia Metropolitan Area; A Cellular Automata Approach
Historical land-use data from the twentieth century was used as input to the SLEUTH land-use change model, a Cellular Automata model developed by Keith Clarke at the University of California at Santa Barbara, to produce projections of urban expansion in the Philadelphia metropolitan area.

Twentieth-Century Land Surface Changes in the Delaware Water Gap Basin, a GIS Snapshot Approach
Methods of integrating land-surface data and measuring change with time are being tested on historical land use/land cover data of the Delaware Water Gap watershed area in Pennsylvania.

Ben Franklin Bridge - Philadelphia

The U.S. Geological Survey (USGS) has created a temporal mapping database of the Philadelphia area for use in land cover change studies. The project uses scanned images dating between the 1940s and 1980s which can be used to analyze the type of landscape which was replaced by growing urbanization. The results from such analysis will shed light on the environmental impacts of the growing Philadelphia/Wilmington metropolitan areas.

The temporal database being used for the study is available via ftp. Further information about this project can be obtained by contacting:
