The Affintransformation can adapt compared with the Helmerttransformation still the relation width to length.
Given
yAP, i xAP, i Co-ordinates of the identical points in the old system yNP, i xNP, i Co-ordinates of the identical points in the new system yA xA Co-ordinates of a point in the old system (before the transformation) n Number of the identical points
In request
yN xN Co-ordinates of the point (yA, xA) after the transformation in the new system)
Calculation
The main focus in the old system
The main focus in the new system
The transformation constants a1 to a4.
an is the change of the graduation, o is the rotation.
