Have a look in the SNAP internal help if you are insecure about different points. There is explained, point by point, how you make a profile for example.
Maybe you should also start a bit earlier with SAR basics before addressing InSAR topics or have a look at the numerous topics in here which are dealing with the same problems:
Hello!
I tried to created a DEM for Atacama desert in SNAP, with the following steps:
Corregistration by using the function “S-1 TOPS Corregistration” (Sentinel 1 Toolbox)
“Interfarogram Generation”. In this step I’m considering the corregistered IW Swath;
deburst
“Goldstein Phase Filtering”;
“Snaphu Export”. I’m not applying the topographic phase removal, since I’m interest in the resulting DEM and not DinSAR,
“Snaphu Import” of the unwrapped phase;
Accordining to the Nest turtorial for Etn…
hi all,
I have unwrapped the interferogram image the whole process was done using SNAPHU export option. the process run more than 1hr. but when i try to generate DEM it shows that no unwrapped phase was found. so how can i solve the problem? can anybody please help me out.
After interferogram generation, topo phase removal, and goldsten filtering in s1tbx using Sentinel-1A data, during terrain correction there is an option to ‘include DEM’. Does the DEM produced by that way a STANDARD way of producing DEM? If not can someone send me your favourite flow steps for DEM generation using master and slave SLC files?
is there any formula exist for converting the unwarpped phase into metric unit… and how we create a 3D map of subsidence…
someone please help me…
