Hi Simone, I consider your first paragraph as the brief, up-to-date description I was expecting (at least, regarding GeoTiff). Thank you very much :-) Regarding the problem with these files, I think I found the cause. It seems a gdal effect (or defect) [1], which causes that some 'weird' coordinate systems don't get correctly stored in the Geotiff. I've exported the same area in EPSG:23030 (using arcgis), and the resulting file could be correctly loaded in GeoTools (and I could see the GeoTiff tags by using [fwtools] tiffinfo). However, it seems that EPSG:3035 is considered by GDAL as an uncommon CRS (despite it is the preferred projected CRS for the European Environmental Agency, for European-scale data). However, this doesn't help me, as I can't change Esri code... So it could be great if we could enable this support in GeoTools...
