By selecting the 1st ORDER option, the user may select the order of
Don't say 1st. Say X or something.
transformation desired: Select order of transformation --> 1st
Order 2nd Order 3rd Order
The program will immediately recalculate the RMSE and the number of
points required.
Linear affine transformation (1st order transformation)
x' = ax + by +c
y' = Ax + Bt +C
The a,b,c,A,B,C are determined by least squares regression based on
the control points entered. This transformation applies scaling,
translation and rotation. It is NOT a general purpose
rubber-sheeting, nor is it ortho-photo rectification using a DEM,
say what to use for those
not second order polynomial, etc. It can be used if (1) you have
geometrically correct images, and (2) the terrain or camera
distortion effect can be ignored.
there should be a way to rectify with just two points BTW.
PS: there should be a way to on the monitor show point numbers next to points in
a group/xxx/POINTS file.
