When I use r.proj to use a DEM in a different location the module shows the number of cells such as this example: Input: Cols: 502 (80961) Rows: 39234 (113148) Output: Cols: 500 (71702) Rows: 39232 (50757) In both the input and output locations the resolution is 1m x 1m. What do the paranthetical values represent? Regards, Rich
