Let assume, that after a PSInSAR analyze we have a vertical displacement solution for both ascending and both descending cases. I know, that combining of the asc and desc solutions makes possible to solve 3D displacements, but there are some points that I don’t understand?
- If I want to get only the vertical displacements by combining them, I just have to calculate a simple average from the solution of the asc and desc?
- How can I put it in practice, if with PS-InSAR analyze I cannot guarantee that the same points are found on asc and decs pictures? (I can unserstand that it’s working if you’re doing simple DInSAR, but a stack of images I cannot see through the process)
Thanks, for any help,
