Hi. I want to use idw to do some multidimensional interpolation. My input (control) points are mostly 2D or 3D (X-coordinates). My output is N-dimensional, with N > 20. According to the documentation, I'm probably not able to use idwbuildmodifiedshepard(): the last column holds the Y-coordinate (1 dimension). Can somebody comment on this? I have been using RBF but I want to test different interpolation methods. |

The only thing you can do is to fit multiple IDW models. Unfortunately, current version does not support multidimensional outputs, and it is not going to change in the foreseeable future. |
