Coregistering with TerraSAR-X

[ABraun]

@tangyin

OK,I have successfully do unwapping phase yesterday, I prepared to use TerraSAR-X data to do three-dimensional extraction of urban buildings. After unwapping phase,I want to know how to generate DEM in snap software.

please have a look at these topics:

DEM generation

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…

DEM creation

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?

Creating DEM

Hi, I am new in S-1 Toolbox and want to know how to creat DEM using L1 GRD product in Toolbox?It is important for me.Thanks.
