I had created about 8 different classes with polygon-samples throughout the entire orthophoto, saved it into a training shape file (admittedly, everything of that with QGIS since I didn't know how to do that with gvSIG), then I inserted both the high-resolution orthophoto (.ecw-file of about 1.3 GB) and the training shape file into gvSIG, pressed the supervised classification with maximum likelihood / minimum distance algorithm in the toolbox, and waited for 2 hours or so. In the end, in both cases I got error messages which you can find within the attached zip-files below (*). I'd love to be able to conduct the land cover classification via gvSIG, but unfortunately I get these errors which impede a successful classification. FYI: I'm using Linux Ubuntu 19.04 with java versions from 8 to 13 (all installed, I tried to perform the classification with java 11 and other versions I think, but in any case the information should be stated within the attached log files etc.). Many thanks for your quick help in advance as the deadline for my Master's thesis is approaching!
