Jesse and Company, I've done a bit more investigation on my problem with the GeoTiff file and what I've found is relevant to some of my earlier comments. I think that the explanation that follows might have some use in furture uDig work. It turns out that the file file I was trying to read is a correctly implemented GeoTiff but that it is in a projection that is not currently supported by GeoTools. Working in my own application (not uDig) I create a GeoTiffReader and attempt to read the file. The reader promptly throws an exception indicating that ProjCoordTransGeoKey(8) is not currently supported." Searching the GeoTools archives I see that this is a known bug dating from 2005, number GEOT-671, which reports that certain frequently used projections are not supported, most notably the Lambert Conic Conformal that was used for the subject GeoTiff (later on, I'm going to go over to the GeoTools mailing list to ask how to go about implementing the projection... so expect more whining on my part). Anyway, I feel that if uDig had a mechanism for reporting this fact when I was first trying to load up the file, I would have understood the program much more quickly and with a lot less digging. And this represents a general pattern of implementation decisions in uDig that I think could be improved. Simply put, the program is uncommunicative. It knows what it's doing, but doesn't share that knowledge with the users. You, the uDig developers, have access to knowledge and insights (and also, non-uDig tools) that are not available to ordinary users or even applications developers like myself. So perhaps it doesn't seem like a very pressing development requirement when writing code. But I encourage you to at least consider if this issue doesn't merit a higher priority in your approach. Again, I wish uDig the best of success and make these suggestions not just to kvetch, but because I think it is a necessary element to obtaining that success I hope the application will achieve. Gary
