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.

Map showing area of coverage The index maps below provide a graphical link to Digital Raster Graphics (DRGs) of historical maps for the Delaware Water Gap Basin from the 20th century (and late 19th century in some parts of the basin). DRGs are the scanned images of published topographic quadrangle maps. Click on a quadrangle of interest to see a list of DRGs available to download in that area. The tif files are georeferenced (GeoTiff), some GIS software packages require a separate tfw file in order to display the georeferenced image.
