Topic: Image cropping issue
I am experiencing the following problem. I wanted to subset a couple of areas from two HiRISE images (usgs jp2 ortho and raw). Before doing the tie point selection I've cropped the images in envi (spatial subset) and I've saved them in envi format. Then I've performed the tie point selection (image to image) over the cropped data and I've saved my tie point file. Then I launched the Tie point to GCPs receiving this error message "Tie Point ... is outside DEM coverage - Altitude set to 0.0". However, I carefully checked the tie points and all of them are inside the DTM boundaries. Do you have an idea on what's going on? I guess something went wrong in the cropping phase.
Thank you very much and happy new year
