Hi! We disabled GeoTiff support for the udig 1.0.0 release (based on justthe kind of experience you have had). The geotools library we are using does not include a very good GeoTiff implementation (when we did get it to work you will find it was very slow).
There are two bright sides to this story: - we are talking with OSSIM - the geotools "GridCoverage" developers are actually focused on implementing a Web Coverage Service for GeoServer. As such they are running into the same problems and are making a lot of progress on performance (as they learn to hack Java Advanced Imaging at a very low level). I have CCed one of the developers on this project in the hopes he can provide an update of GeoTIFF support. I hope our reasoning for not supporting GeoTIFF (until it is good) makes sense. We are an open project, so if you did have anyone with GeoTIFF and Java hacking ability we would welcome assistance in this matter. Cheers, Jody PS. You are not alone - at the OSG'05 conference GeoTIFF was the most requested feature _______________________________________________ User-friendly Desktop Internet GIS (uDig) http://udig.refractions.net http://lists.refractions.net/mailman/listinfo/udig-devel So I gather there two problems (?) 1) dissattisfaction with the geotools geotiff code 2) Changing of the interfaces Why not use Gdal for the geotiff (a.o.) part. We build access from Java to Gdal using JNI based on the geo-api interface. Could read, write and create gridcoverages from java in there with reasonable performance. We did not finish it entirely but that has more to do with the changes that will happen in the geo-api interfaces with respect to ISO 19123 (we did not want to spent more time on implementing things that will change anyhow). In GeoTiff (internals) itself we have experience, coded our own conversions from geotiff to (at that moment) our internal ILWIS format. So the knowledge about Geotiff is ok I guess. With respect to interfaces I think we could contribute, many years experience on both the practical use of gridcoverages and the software side of it (and defining our interfaces for it). So whom should I contact there to talk with. The point is we would like to use Udig as base for our further developments. At the ITC where I do my work I think that the usage of raster/vector is about 70/30, a package that does not support rasters is difficult to sell here.
