This requirement will continue the work already accomplished by extending the Clarke cellular automation urban growth model by modifying the software to include forest land, agricultural land, and wildland; assessing the scaling properties and scale-up stability of the Clarke cellular automation land cover change mode at multiple scales; using government furnished temporal urban mapping database of the Washington/Baltimore region; using government furnished data from the Advanced Very High Resolution Radiometer (AVHRR), the Defense Meteorological Satellite Program (DMSP), and Geographic Information Resource Analysis System (GIRAS), scale up the Clarke model to a prediction of future land cover patterns of the conterminous United States (48 states); predicting geographic extent of urbanization to the year 2050 and estimate the rates of loss of other land covers to urbanization, and evaluate the model's ability to scale up from continental results to global predications using AVHRR and other government furnished data. The requirement shall be completed within 12 months after date of award. Based on information available at this time, and in accordance with 41 U.S.C. 253(c)(1), implemented by FAR 6.302-1, the Government considers the item specified as a sole source from University of California-Santa Barbara, Santa Barbara, CA and proposes to negotiate a contract with that institution on that basis.
