OK I guess I have to convert them. Hope I can find a batch command. 2) Where can I find documentation on how to stitch my images together? I have not found the documentation for that process yet. Once you have georeferenced all your images, you can create a virtual raster to adress them as a single layer. Off course, stitching them in gimp is also possible. The images will be georeferenced to the reference image. From your description of what I need to do it appears that I can't do what I want. (Coming from that other GIS software.) I want to click on a point on the reference image and then click on the same location on the distorted image. Do this 3 or more times (not in a line) and then tell it to transform. Is there some other package/program that will do this? I don't think Gimp works this way. Greetings, Andr?
