Description

I just found out that r.resamp.interp fails for both bicubic and bilinear interpolation. It makes maps with all NAN values. I used the new NC data set and produced a set of random elevation points (raster and vector), then tried to use these in r.resamp.interp. The nearest neighbor routine worked, but the others did not. I tried the original raster point map and also tried one that I converted to a CELL map. Neither gave usable results. FWIW, I got the same result using r.bilinear.

I'm having a very difficult time putting together a class on interpolation using GRASS today. v.surf.bspline does not work, 2 of the 3 methods in r.resamp.interp do not work. r.bilinear does not work. Pretty bad press.
