Hi all,

there is a new module in grass7 for raster interpolation called
r.resamp.bspline, based on the lidar tool methods. NULL cells are
filled on the go, no need to fill them first. Alternatively, the
module only interpolates NULL cells in the input raster, running quite
fast in this mode. The output raster map can then be used to fill NULL
cells in the input map (r.patch
output=gapfilled). Please test!
