MapCalc should most probably do it but I was wandering about a built in constraint in that program; it works exclusively with non-projected data. That could have some bearing on the precision of the calculations if there are based on simple raster positions and not on actual distances. One must remember that MapCalc main application is for small scale projects (micro-farming, resource management...) where cell differences in metric size should not be an issue.
Does anyone have some experience on this issue? Is it a real drawback at some scale?
