<br>
linear transformation (from my practice) use three unknowns<br>
offset (Easting, Northing) and scale. No rotational angle.<br>
The linear is not a good name for it.<br>
E' = Eoffset + scale * E<br>
N' = Noffset + scale * N<span class="HOEnZb"><font color="#888888"><br>

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