Image differencing has long been used as an effective change detection technique for coregistered digital remote sensing datasets. One image is simply subtracted from another image on a pixel-by-pixel basis. As applied to gridded DEMs, the result of image differencing is a differential surface, which is a measure of the spatial distribution of mass displacement. In a differential surface, the...
