Comment(by kyngchaos):
Markus, see my patch. It's very similar to what you describe. A couple
notes/questions:
I didn't completely understand the description for the sparse option, but
it didn't look like it was needed here. Now it looks to me like it's
essentially a mask option, like the maskmap option in v.surf.rst. For
now, the mask is implied when the results are patched into the original
raster. I guess a mask option (if sparse is such) only makes sense if it
reduces processing time by ignoring the masked areas.
The description says 1 * resolution was good for regularly spaced points,
which is what we get from a raster. Why 2* in your method?
For the lambda, the docs are unclear what orders of numbers have effects,
beyond "the larger the number the more smoothing applied". The default is
one. You say 0.001-0.01 work well. I figured 1 was something like 1*, or
no smoothing. Can you clarify this option?
