Topic: Worldview 1-2 Nadir angle

Hi all,

I would like to ask you a question related to nadir angle of worldview 1-2 satellite images in different periods. To determine the horizontal displacements, have we encountered any problem in case off-nadir angle is about 18-21 degree (between 18 and 21 degree both of two images) for slight mountain areas. In addition, are there other criterias to get consistent and accurate results?

regards,

For accurate results with high incidence angle, you need to solve a full 3D problem using two stereo pairs (4 images). This code is not publicly available at this point.
