Point Mapping

Your main task when using any rectifier is mapping points on your photograph to points in the real world so you need to become familiar with the Point Mapping dialogue box. You should also look at the section on taking measurements for some ideas about establishing your coordinate system.

Placing the points in the source image is generally most easily done by establishing them with a double mouse click near where you want them then moving them into position in the window of the Point Mapping dialogue box, where you can zoom in for precision placement.
note: If you are having trouble placing the point exactly where you want it the arrow keys will move it in one pixel increments after you have selected it while you hold down the left mouse button.
