I am still somewhat stuck on this. I have defined a face (3-d area) and it seems that very few of the vector functions can do anything with a face like that. Any other suggestions for doing these types of calculation? Thanks, --Adam On Jan 2, 2009, at 5:14 PM, G. Allegri wrote: I

Is it possible to use grass to calculate the volume of a part of a 3-D vector object? What I mean is if I have a mountain, for example, that is defines in one vector map. Then, in another map, I define an area (a plane for example). This represents a slice through the mountain. Is it

I don't know the latest devlopments on the 3d vector system, but I would convert the vector to rasters (2d or 3d) and then use map algebra... giovanni 2009/1/3 Adam Dershowitz adershow...@exponent.com: Is it possible to use grass to calculate the volume of a part of a 3-D vector object? What
