Hello

The function Automap has been of great help to me and i have set it up
to perform cross validation for variables over continental USA.

Essentially this is a very large dataset with about ~3500 points.
There were many other dimensions , temporal etc that i wanted
to explore but i could not get R packages setup  on univ supercomputer
due to technical issues.

This cross validation does not perform on my PC due to lack of computational
units.

Core 2 duo, 8 gb RAM. for Thin plate splines and kriging which are my
primary interest. It is obviously impractical to have so many points.

I am dividing this dataset into smaller units and targeting ~300 points per
polygon for analysis. Can anyone advise me on the influence of
number of points on the computational needs for TPS and kriging
based on their personal experience.

I do know that Thin plate splines and Kriging are computationally demanding
and my dataset is huge. Moreover it seems infeasible to do cross validation
on it.
 If anyone has any specific advice based on personal
experience will they be willing to exchange a few emails?


Thanks
