Hello,
I would like to know, if the proj-libary might also have a function to give a
projection of images or scanned maps where the geographical projection is
unknown but where only some reference points are known.
For example I have some aerial images where I exactly know at least 4 or even
more points on the ground with there geographical coordinates.
I would like to have a "projection", like latlon2xy and xy2latlon for all
points of the image according to the known reference points.
Something like polynom-approximation?
Is there such thing already in proj?
Best regards,
Thomas
