[GRASS-user] v.surf.rst limitations?

[Michael Perdue]

Carlos,

To the best of my knowledge, the only limitation on v.surf.rst is  
imposed by the limits of your hardware. IE, your probably running  
into memory allocation problems. You can try increasing your swap  
space, but be aware that v.surf.rst will take a painfully long time  
to process that many points. Alternately, I'd recommend you give  
r.in.xyz and v.surf.bspline a try.

Cheers,

Mike
