Geomod
Institution: Clark University
Principal Investigators: Robert Gilmore Pontius Jr
Description: Geomod is a land change model that simulates a one way change from one category to one other category as time progresses. Geomod allows independence between the prediction of the quantity of land categories and the prediction location of land categories. Geomod is fully incorporated into the GIS software Idrisi, therefore it encourages appropriate validation and uncertainty analysis. See the related publications for guidance on validation and uncertainty analysis.
