Hi List, I have an ECW-file which I convert to GeoTiff using gdal_translate. This GTiff file I use in GeoServer as a base map.
This is working great, but because I compress the GTiff with JPEG I get white borders around my area. To solve this I can clip my GTiff with the outer line of my original ECW file. My question is how to create such an outer line. I can of course draw it myself using QGis or MapWindow but I'd prefer to let it calculated. Can GRASS do this? If so which command do I need. Thanks, Paul
