Topic: Optimize GCPS file
I've got the shaded dem image and the first image to orthorectify.
I select 20 tie points between these image and i use all the suggestion of the cosi corr guide. But when I go to optimizate the GCPS file i see that there is not convergence.
All the other steps are correct and i will obtain the final correlation of the tu orthorectified spot image of the sample but the results are not realistic in vector field because i compare it with the results of the guide.
Is this due to the lack of convegence?
How can i do to obtain the convergence of gcps optimum file? I used all the suggestion of the guide: the tie points were generated with criterion.
Help me please
