Study area is an urban area and I know exactly which building’s foundations are unstable over this area.

Hi!

I am processing 39 Sentinel images and after set orbit step I checked the footprint of subswath. After I changed the subwath and Google Earth showing me same footprint for different subwaths.

Then after master extraction software gives me an error with slave extraction.

Could you please have a look what I am doing wrong?

Thanks,
Venera

Hi Daniele,

thank you for your quick reply.

Do I need to use small area processing module for that purpose?

thanks,
Venera

I solved my problem with co-registration. I’ve just realized that it was due to corrupted downloading of Sentinel images.

However, do you have some general recommendations or tips to get reliable results from Sentinel data processing (parameters and so on)?
I am doing processing Sentinel 1 data over…[Read more]
