[GRASS-user] Thin plate spline for climate point record interpollation?

[Dimos]

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
