Hello, I have contours (about 5000 polylines) and I need to interpolate those with Spline. But Spline function can only interpolate points, and my contours are polylines. I hope that anyone has a solution to my problem. Thanks a lot!
See TopoToRaster (it uses inter alia thin plate splines) or convert your contours to points. however, you might then have "steps" in your output surface.
