About the selection of images

Interfremetric pairs for DEM generation

Firstly, they need to be of the same track (relative orbit), that means they must cover the same area, at least in range direction. Images which only partly cover the same are (perpendicular to the flight direction) can not serve as pairs for interferometry. Secondly, for DEM generation small temporal baselines should be preferred. A pair of Sentinel-1A and B can be 6 days apart at minimum. A pair of 2 Sentinel-1A scenes is 12 days apart at minimum. The longer the time between the images the hi…

It is based on NEST so some parts of the GUI look a bit different now but in general these are your required steps.
