I'm trying to change a project from ERDAS Imagine (LPS) to PCI Geomatica. I have the block-file which contains 2 stereo-images, a reference image and >100 GCPs/TPs. As I don't want to redo all steps, I thought I could either import the .blk-file directly in PCI or else, I export it as a .prj-file from ERDAS. However, I don't know how to do any of those possibilities. Can anybody help me? The goal would then be to generate a DEM with the stereo-images and the included GCPs.
