1. A geospatial modeling system comprising: a geospatial model data storage device; and a processor cooperating with said geospatial model data storage device for selecting and transforming a reference sample of a geospatial model frequency domain data set into a corresponding reference sample geospatial model spatial domain data set, the geospatial model frequency domain data set having at least one void therein, iteratively inpainting data into the at least one void in the geospatial model frequency domain data set to generate an inpainted geospatial model frequency domain data set, selecting and transforming a test sample of the inpainted geospatial model frequency domain data set into a corresponding test sample geospatial model spatial domain data set, and comparing the reference sample geospatial model spatial domain data set and the test sample geospatial model spatial domain data set to determine whether to stop the iterative inpainting.
