DEM problem

Hello everyone
I’m trying to make DEM for some archeological areas but when i do the coregistration the slave image disappear…what is wrong with my method?
I take data from the same satellite in another day, i do top split for both, i apply the Orbit, After the back geocoding i have only the master, if i open the slave Is empty…help me pls

please check if your SNAP version is up to date (Help > Check for updates) and use SRTM 1Sec instead of SRTM 3Sec in the back geocoding.

Thank u…It worked :heart_eyes:
