[Live-demo] Still add some demo data?

[Massimo Di Stefano]

Hi All

about raster data, look at the ossim script it already
download 3 band landsat images and the srtm data (90m) 
the zone i choose is spain/barcelona 


i guess this data should be easy reusable by other application.

p.s.
apologize me for the complete absence from the list (i know there is a lot of work to do)
i had to defend my master degree thesis the last week 
... i'm back :-) to help a bit for what i can
