Why my DEM made by S1A data have no elevation value?

[ABraun]

I made a test with the first two scenes.
I used S1 TOPS Coregistration with ESD

• Subswath IW3
• VV Polarization
• Bursts 1-3
• SRTM 1Sec (AutoDownload) for the BackGeocoding

and left all other parameters as standard.

Worked out well.
