Finally,

I am, sort of, free again :-). I have prepaired a grass-location
containing the 3 modis bands I've used for all PCA related examples. I
will eventually upload them in gregis [1] but if there is another place
(GRASS-wiki?) to upload them would be also ok.

I have received a copy of the book. Just excellent. I would like to see
more books like this one :-). Congratulations to the authors.

Cheers, Nikos
