How to run the PGE:

To run the merged track stitcher you need to facet on S1-GUNW-MERGED-AOI_TRACK data products

(WARNING: The PGE is iterative so make sure you are faceting on a handful of products, not 1000+)

Example faceted URL to TOSCA

The PGE will then take the s1-gunw_urls localize all the GUNW products into the worker’s local directory, from the hysds-io.json.aoi-merged-track-stitcher file.

Main Stitch Function

The inputs stored in json file ifg_stitch.json & read by the MergedTrackStitcher.stitch() method:

  • filenames is ordered a array of raw GUNW files

  • direction is hardcoded to along

  • outname is hardcoded to filt_topophase.unw.geo
