Hi
I am a computer science student and got to do a semester project in
the area of surface reconstruction. I would want to relate my project
to GRASS/GIS/terrain analysis. I went through the wish list of
projects in the GRASS website but didnt find anything much concerning
interpolation or surface reconstruction problems. Is there any scope
for a project in this area ?
Thank you.

You could try and get s.surf.krig working properly, or some of the sites modules that Radim recently ported to 5.7 that have inefficient algorithms. Search for s.surf.krig and s.kcv in some of the recent mailing list archives for some ideas.

or even better you could try to do build support for TINs - we don't have that at all
and that would be more related
to surface reconstruction problems than kriging (I already expressed my
opinion that kriging and geostatistics is best served through bridge to R,
unless we would get somebody with long-term commitment to this area).
Or you can contact me and let me know in more detail what you want to do,
as we are doing a significant update of the spline-based surface modeling tools
for GRASS and there is quite a bit of work to be done there too.

You should probably coordinate TINs with Laura, no point in duplicating
efforts.

Note the current v.surf.rst in 5.7 still needs the 'deviation' output
updated to use the 5.7 points mode. Currently devi= doesn't export
anything useful. Shouldn't be too much work but should teach you
something about the 5.7 vector API.
Not sure if the treefile and overfile work either(?).
