Hi all I've been searching high and low for an answer to an issue I'm having with a DEM created in ERDAS LPS 2013, our DEM is completely inverted!
The river valleys are now ridges ~700m and the ridges are the valey bottoms ~300m!
A screen shot is here
There are ten images in three flight lines with nine GCPs per image and ~16,000 tie points shared between all images.
Any help would be greatly appreciated, the ERDAS help and forums are completely useless!!
Thanks!!!
