Ornlu, Interesting concept! Good idea. dems: if you can convert an image to a .dem file somehow you could save sequential images that way. there is a free software that will put sequental dems together into one image. I forget what it is called but if you search this forum using the keyword dem you might find a reference to the program and it's URL. Ultima VI: it might work - one of these days I'll have to check it out.
