general workflowΒΆ
The workflow and steps here are built partly from the steps outlined in the excellent Historical Orthoimage tutorial, written by Luc Girod. It has been modified to include specific KH-9 pre-processing steps, as well as optional historic air photo preprocessing steps for historic air photos.
The other main difference is the use of spymicmac.register to find control points automatically, using an orthorectified image and external DEM.
