• once the AOI has been created, facet on the AOI in Tosca and run the following jobs:

  • acq scraper jobs

    • Action: AOI based submission of acq scraper jobs [develop]

    • Queue: factotoum-job_worker-small

    • Result: this job will submit individual acq scraper jobs over the AOI

  • IPF scraper jobs

    • Action: AOI based submission of IPF scraper jobs [develop]

    • Queue: factotoum-job_worker-small

    • Result: this job will submit individual IPF scraper jobs over the AOI

• these update the acquisition-S1-IW_SLC dataset

• Notes:

  • An “overloaded” term is AOI and track. Here are the definitions:

    • An AOI is the area which we want to cover with GUNWs. The SLCs to be downloaded and paired will be according to the enumeration strategy determined by the enumerator submitter below.

    • A track is the path in which the satellite follows and repeats during its orbits around Earth. Here is an image for Sentinel 6’s tracks. These track numbers are called path numbers in ASF Search (see the Filters menu; the example in the linked search shows Track 48 in January)

    • How are they related? We purposefully create AOIs that align with a particular track so that all the SLCs come from a given track. This is ensured in the enumeration because we have a minimum coverage threshold for SLCs and only those within the track will satisfy that threshold. Note that every SLC is collected on a given track so every SLC has a track number.

    • We can facet on tracks within Tosca using:

      • metadata.track_number:<track_number> or metadata.trackNumber:<track_number> (depending on the ES dataset)

  • After creating AOIs, the spatial extent of the AOI dataset in tosca will be the single most important way to query the subsequent downstream datasets related to an AOI. Here is the rough process to do so:

    • Select the recently created AOI in Tosca

    • Click Query Region within said dataset

    • Facet on other dataset or query strings for further filtering.
