Dear list,
I have successfully included natural neighbor interpolation in my
mapping routine via r.surf.nnbathy: it seems slower (is that OK?) than
v.surf.idw but sounds a lot more robust from what I have read around --
this is very useful if the interpolated raster is to be used for further
analysis, beyond visualization.
Currently, the interpolated raster output I get from r.surf.nnbathy is
confined to the convex hull delimited by the outermost input
points/cells. Would there be a way to extend the interpolated raster to
the whole current region as in v.surf.idw (in principle this seems
possible: outer Voronoi cells just get bigger)?
By looking at r.surf.nnbathy code and nnbathy --help, it seems that
nnbathy should produce a rectangular grid of <cols> by <rows>. What am I
missing?
Thanks and regards,
Luigi
