However, as the cell resolution increases by reducing cell size, the number of rows and columns in the raster representation also increases. The size of raster representations of land-use problems is often a determining factor in the type pf methodology used in solving such problems. Previous land-use allocation models integrated with a raster GIS have used either decision heutistics of exact methods based on linear programming models. The former is fairly scale independent but produces only approximate answers, wheras the latter produces optimal solutions but remains more scale dependent. This paper presents a specialized dual simplex method adapted to the generalized assignment problem that can used to solve large-scale land-use allocation problems. The dual approach only requires that information for one pixel be stored at time thus allowing solution of problems based on any size raster database.
