Hi Ron, we tend to use geotiff with various compressions. A decent alternative to ECW is geotiff with JPEG compression at visually lossless level (i.e. lossy but almost invisible to human eye) with raster masks to mitigate compression artifacts.
The alternative is to set the transparent color in GeoServer to black for ECW. Regards, Simone Giannecchini == GeoServer Professional Services from the experts!
