Re: Rotating Aerial Imagery Bands

Hi,
I think that u have to rectify the other band layers (that are rotated
at 180 deg) and then do layer stacks. I think instead of rectifying
many GCPs, take only the upper and lower lat & long for rectification.
I used the rotate utility of view to rotate the images, but by saving
this file as .img it gave the same result(rotated layer). Inform me plz
if u find some other way of doing this.
