I have a problem: I'm trying to georeference a satellite image (ASTER, Erdas Imagine file *.img) in QGis. I have georeferenced with QGis before and never had any problems. The file is georeferenced already in UTM 17N WGS 84 but very very badly, so I need to re-do it.
I have opened the file in QGis and set the project coordinate system to UTM 17 N, then I have added a basemap with open layers and used the basemap (Bing Maps) to generate GCPs using the Georeferencer tool. I set the output coordinate system to UTM 17 N, too.
Everything looks good, but when I finish the georeferencing the file ends up in the wrong place (or in no place at all rather, the basemap disappears when I zoom to the layer). Sometimes it doesn't even display. I have tried different coordinate systems, re-sampling methods, also saved the file as .tiff - no changes. I have tried it with other raster files, they always worked well. Does anybody have any idea what I'm doing wrong?
(Just in case: I have tried with ArcGis, that doesn't work because I don't have a BingMap access key and the basemap I can access has a worse resolution than my ASTER image. Same problem in Erdas, theoretically I could use Google Earth for georeferencing there but I'm using a computer at my university and the Google Earth tool isn't working).
I'd be very very glad if anybody has a suggestion, this is for my bachelor thesis and quite important, and I've spent two days already trying... :)
