Topic: Orthorectification of images with high off-nadir angle
Is it correct that if I have two images with the same off-nadir angle higher than 5 degrees that then I will need to use stereo pairs. Or is it only if the difference between the off-nadir angles of the images is higher than 5 degrees?
Can I compare images with different resolution, one with 5 m and one with 0,5 m resolution?
I have been warned of using spot 5 images, is it some problem with them in cosi corr?
As from the posts in the forum is it true that I will need DEM for the whole image or can I use DEM only for the area of interest, if the images I compare don´t cover the excactly same area how do I then select the area I need DEM for?
