The On-Demand aoi-track API is a higher-level abstract for end-users of how to manage AOIs.

This API maps the concept of “aoi-track” to front end UI, onto the back-end dataset=aoi-track.

See Standard Product S1-GUNW Processing Pipeline for more details on the processing pipeline.

Implementation Notes

create new aoi-track

This API will call the mozart api to submit new job “create_aoi-track:develop” to create a new AOI using conventions for aoi-track.

Note: dataset=area_of_interest does not have track info in the dataset. So we can store track info, orbit direction, user info, etc. either in the AOI’s met.json, or even easier by storing it in string tokens that are part of AOI dataset naming convention for this AOI.

Approach can be to call Mozart API to create new dataset=area_of_interest but with dataset ID of convention “aoi_track-<orbit_direction>-<track_number>-<username>-<YYYYMMDDTHHMMSS>”. This will result in publishing new AOI to GRQ with this naming convention.

See an example of how to submit mozart api job in python here: https://github.com/aria-jpl/scihub_acquisition_scraper/blob/develop/crons/aoi_ipf_scrape_cron.py

Submits sync catch-up jobs for IPF for all acquisitions in that aoi-track.

Assumption: Create AOI of high target areas for the system to keep-up IPFs.

list aoi-track

query GRQ for all dataset=area_of_interest , but then filter results for dataset IDs that starts with “aoi_track-*”

get aoi-track

query GRQ given aoitrack_id
