Hi everyone, I have a problem with making a border around a Geotiff transparent. My Geotiff is a satellite image and I’m serving it through Geoserver 1.7.3 via the KML reflector to Google Earth. When I use the raster sld, it shows up fine - but with a huge black border. However when I switch to my transparent_raster.sld (attached) nothing comes up in Google Earth. Gdalinfo shows the following truncated information about my file. I have seen and read the archives regarding transparency and Geotiffs but I’m obviously missing something, so I’d be grateful if anyone can shed any light about what I’m doing wrong with either my file or sld.
Many thanks
