The PSGM is an ArcView GIS compatible application that allocates future growth into available land based on user-defined parameters.
The growth allocation portion of the PSGM assigns growth (in the form of acres) for each land-use category and a time step to the composite suitability grid (CSG).
A road network is a required model input for the PSGM. The level of detail can vary depending on data availability and output requirements.
