[Gimp-user] transform questions

I have an airphoto image and a trail map image, and wish to overlay them so the
trails show appropriately on the airphoto.  Have set up layer for each, and have
to move, rotate, scale, the trail image hoping to line things up.  It requires
multiple tweaking (each affecting another), and the result is not very
satisfactory.  Is there a better way?  Ideally pick similar locations on each
layer image (say road intersections or geographic feature) and the program will
scale, rotate, etc the layer as appropriate to get them aligned ?
