We have released a test / alpha version of the 2D GCP generation tool for Windows. You may experience a bug or two but overall it should be functional. Let us know if you have problems working with the 2D GCP utility or have additional feature requests.
Essentially, you want to create a list of images that the GCP appear in and load them into the tool. The images must be geo-tagged. Once, you've loaded all the images you can navigate between the imagery to add the 2D GCP locations. The GCPs appear in a small text box on the lower left side. When you've completed all the GCP you can save this list as the 2D GCP text file. The 2D GCP file is one half of the required GCP data needed for our processing chain.
Let us know if you have any questions.
