Landsat ETM+ Gap filling & WELD data

Hey

So, the first question is - is there an implementation of the newer
algorithms for Gap filling in any R package?

If not, I would be available to work with an expert to try to develop it
here - some of the actual IDL code is available through Dr. Xiaolin Zhu's
page: http://geography.osu.edu/grads/xzhu/ , so would it be so costly to do
it here?

The second is WELD data, I am absolutely confused on what is the projection
they use on that dataset.. can anybody enlighten me?


All the best!
Nuno
