There is a new feature in orthoengine to automatically extract the projection information from the input data. Open a new Orthoengine project and enter the correct information in the Project Information window. Click OK. When the Set Projection window appears you can click Cancel. A popup will appear to let you know that the projection information will be read in directly from the first image. After you have added your first image to the project you can reopen the Set Projection window and see that the information has been filled in.
If you have any further questions please contact PCI Geomatics Support (firstname.lastname@example.org).
