|
|
I have difficulty understanding the concept of calibration with two known points (top-left and bottom-right). The manual is rather sparse on the subject.
Does it mean I will have to define the two corner points and find their coordinates somehow?
What happens if I choose two other points? Will I be able to move outside the rectangle defined by the two points?
What are the limitations of the method? I presume it only works with certain map projections. |
