1. A geospatial modeling system comprising: a geospatial model data storage device; and a processor cooperating with said geospatial model data storage device for windowing geospatial model spatial domain data to define a plurality of windowed geospatial model spatial domain data sets, transforming the plurality of windowed geospatial model spatial domain data sets to define a plurality of corresponding geospatial model frequency domain data sets, each having at least one void therein, inpainting data into the at least one void of each geospatial model frequency domain data set to define a plurality of inpainted geospatial model frequency domain data sets, and reconstructing the plurality of inpainted geospatial model frequency domain data sets into an overall reconstructed geospatial model frequency domain data set.
