WebA thin plate smoothing spline is a generalization of the cubic smoothing spline, and depends on two parameters: m, the order of the derivative penalty, and , a parameter controlling the amount of smoothing. For the case of one dimension and m = 2, the estimate reduces to the usual cubic spline. Webv.surf.tps performs multivariate thin plate spline interpolation with regularization. The input is a 2D or 3D vector points map. Values to interpolate can be the z values of 3D points or the values in a user-specified attribute column in a 2D or 3D vector map. Output is a raster map. Optionally, several raster maps can be specified to be used ...
