Standard processing parameters

Falk Amelung edited this page May 24, 2020 · 4 revisions

We are trying to use the following parameters for consistency of the processing results. The Intermediate resolution parameters are similar to the ARIA Standard Products. (Low res and very low res need to be finalized)

(We need to deal with ESD similar as ARIA: Default is 0.8. If coherence is too low and ESD fails, threshold is relaxed in steps of 0.05 until 0.5 is reached, after which processing is done using orbit information only. From David Bekaerd: The ARIA project wraps around ISCE, for additional functionality it would need. e.g. Data/DEM staging, pairing decisions, orbit decisions, ESD fallback, naming conventions etc. The ARIA code is all on public github if you want to have a look. In short, it will check if the ISCE code runs or errors out on the ESD step, and the makes decisions based on that. repo is here: https://github.com/aria-jpl/ariamh Standard product specific is here: https://github.com/aria-jpl/ariamh/tree/develop/interferogram/sentinel )
