For the past few years 3sec dems (with sentinel data) has provided good consistent results, but as of recently I couldn’t get coregistration to work with 3sec dems, so I switched to 1sec dems and now my results are hit or miss, with some data looking decorrelated. The first image below is of a successful run of my process, but the follow up image is of an interval one month earlier, and the near-uniform lines I’m seeing I’m being told is an error with the data, or possibly an error with the process concerning hardware and space/storage issues. Is there possibly a space/hardware/equipment issue happening now that I’m trying to use the 1sec dems for processing? Or could it be the type of dems themselves?
I’m currently working out of Snap v6, what are the computer processing requirements for v8? A coworker tried using v8 but said “Snap is unable to apply any orbit files to the data processing” and his work around was to downgrade to v6.
Thank you all for your time and help!
