Dear All,
- Single-pass InSAR systems (TanDEM-X) will be good for producing topographic maps and repeat-pass InSAR systems with a small baseline will be good for displacement maps.
Note that the displacement disappears in single-pass InSAR systems.
Am I right? - If we want to know about the displacement, one interfrogram can be enough? When we use two interfrograms? Using two interfrograms is only for topography purposes?
- As I know topographic part and DEM has information about the hight but how about the displacement? As I read the displacement can show deformation in vertical and horizontal or combination of both.
What is differences between topography and vertical deformation?
Cheers,
Marjan
