Ah right, I didn't think to the geotools <--> GDAL bridge. Yes, it is unfortunate that the design of geotools (ImageIOExt actually AFAIR) for image format requires new code to be written each time. I haven't yet looked at the code to understand why it is such. However a possibility would be to write a VRT ImageIOExt plugins, and that way you could open any supported GDAL dataset by priorly "wrapping" it in a VRT. > > Regards, > B.
