Dear Grass Users,

How to do thin plate spline interpolation with Grass
GIS (ex. Anusplin
http://fennerschool.anu.edu.au/publications/software/anusplin.php)
using:

-Lat, long and elevation as the 3 independent
variables
-Temperature or precipitation as dependent variable
-1 KM elevation grid
-Irregularly spaced 30 year climate records (POINT
DATA)

To create a: 1 KM resolution climate surface for each
dependent variable

Thanks,

Dimos

v.surf.rst or v.vol.rst for the 2D and 3D cases.

see http://grass.osgeo.org/wiki/RST_Spline_Surfaces
and help pages for those modules.

output layer is typically called "elev", but it can be any variable.
