Unfortunately not. I never played with raster italian data, believe it or not, my data experience is only with freely available USA data. Can you provide us a sample by private mail? Also, which version of Geotools are you using? I suggest to checkout and compile 2.3.x branch if you haven't already done so. Raster support in 2.2.x is rather poor, and quite a bit of improvements got in 2.3.x after the 2.3.0 release. > PS: another question: the projection is taken by default in lat/long, if I do > not > supply a .prj file with the info in it.

Most data coming from NASA and similar sources in in fact unprojected WGS84 data. Cheers Andrea ------------------------------------------------------------------------- Take Surveys. Earn Cash.
