Is there a metadata schema for representing all the metadata information needed to represent a single TOPS burst that is supported by SNAP. I’m looking for support for two operations - InSAR and RTC (with thermal noise correction). Essentially, an equivalent of https://github.com/isce-framework/isce2/blob/main/components/isceobj/Sensor/TOPS/BurstSLC.py but with some additional metadata like the noise vectors and sigma0 LUT.
- After some experimentation, it looks like BEAM-DIMAP might be the only option available that can carry over all the necessary information. Is this correct?
- Geotiff + XML seemed promising (easier to implement) but it did not carry over enough of SAR metadata for later processing. Is my interpretation correct?
- Is there a schema available that clearly labels what pieces of information are mandatory (for BEAM-DIMAP or other format). One can possibly reverse engineer this with “Read” + “TOPSAR-Split” + “Write” to BEAM-DIMAP. But if there is an authoritative reference - it would be helpful.
- In particular, what part of the “original_product_metadata” is mandatory, if one were to use this format?
