DEM Interferometry with SLC

Did you take a look at this whole topic of DEM generation?

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?
