The SLEUTH model was developed by Dr. Keith C. Clarke at UC-Santa Barbara and integrates 2 sub-models, the Urban Growth Model (UGM) and the Deltatron Land Use/Land Cover Model (DLM). The disadvantage of SLEUTH is that it currently only defines built-up land and does not model intra-urban categories. For more information on SLEUTH please refer to http://www.ncgia.ucsb.edu/projects/gig/.
Currently our main data source for SLEUTH is the USGS Urban Dynamics Data, which was received in collaboration with Roger Barlow (USGS), Ann-Margaret Esnard (Cornell University), Janet Tilley (USGS), and Dan Sechrist (USGS). The dataset was developed for the New York metropolitan area and includes data at three resolutions: 10-acre, 1-acre, and 35-meter. 70-meter data was derived from the 35-meter data.
