I wonder if somebody knows a detailed reference on geographic transformations in particular the Affine one. How do the B and D parameters depend on pixels x and y? Are they constants or functions? Working with simple aero photos it seems that the geometry - optical deformities make D and B to change inside the scene. Helps welcomed Thanks Dyan C.
