Curvature ranges

Discussion created by on Mar 29, 2014

I'm analysing an 80km2 fjord area with sills and basins (up to 163 m depth). I have used the curvature tool to create curvature, profile curvature and plan curvature rasters. However I'm getting ranges of -90 to 106, -76 to 62 and -48 to 50 respectievely, which are too high, i belive they should be in the order of 0.1, or 4 if its an extreme relief area which I don't think it is.

Does anyone know why would that be?
