Dear all, I have some aerial photos from different time periods that I would like to register acurately in MapInfo - acurately enough so that I can digitise river channels over it and look at the change in extent of the channel. However when you zoom in on a black and white aerial photo the boundaries that you would like to use as points to register are way too fuzzy to do it accurately. I set the dpi so that the file is about 1-1.6MB, jpeg/gif image. (I am soon to have access to a computer with 36 GB, 256MB of RAM, Pentium 4).
Does anyone know how this is usually done? (without buying extraordinarily expensive software) cheers, Suzanne.
