	I vectorized some maps in AUTOCAD, brought them into grass and, using
v.transform, rectified them to the proper UTM's.  Using d.measure I took the
co-ordinates of several building corners of the vector maps and used these to
rectify some digitized air photos. The problem is, when rectified, the image
is blown up about 20 times and cropped to a very small region of the entire
photo. I've checked the region and it agrees with the co-ordinates ( ie. the
iamge fits the region ) but still it won't work.
			- thanks for any help, brian
