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 Il giorno 27/lug/2010, alle ore 21.52, Hamish ha scritto: > Johan Van de Wauw wrote: >> In that case maybe some raster data should be added to the >> mix: the only raster which is available now is an already >> rendered image, which is not very useful if you want to show >> some raster processing capabilities. > > for my 2c, I like the idea of including a SRTM tile or two > for raster GIS programs to use in their tutorials.
