Dear Sajid,
checking the source of the plugin I realized that different scales are
used in easting and northing direction. So the formulas look like:
E' = Eoffset + Escale * E
N' = Noffset - Nscale * N
The minus in N formula is because of the different axis direction in the
screen coordinates
Hi Zortan
Thank you for the reply.
Would be great to know, how this Offsets and scale is calculated from a set
of GCP's.
Any idea?
Regards
Sajid

Dear Sajid,
linear transformation (from my practice) use three unknowns
offset (Easting, Northing) and scale. No rotational angle.
The linear is not a good name for it.
E' = Eoffset + scale * E
N' = Noffset + scale * N

Hi,
Can anyone give me hints on statistical background behind linear
transformation in Georeferencer plugin?
I want to know the formulae used to calculate the residuals while using
linear translation.
Any related paper/material on which it is developed??
Thanks and Regards
Sajid
