This was an older processing pipeline that reacted on AOIs and used qquery to pull in SLCs wholesale to trigger processing of intermediate products only for DPM v1 and FPM v1.

Description

Facet Input(s)

JPL Tested Repo/Branch

1

Create event AOI (Add AOI)

area_of_interest

Creates an AOI with region coordinates, start_time, end_time, and event_time of event.

AOI Coordinates (bbox)

create_aoi:develop

2

Acquisitions scraper

acquisition-S1-IW-SLC

Creates a metadata dataset of Sentinel-1 acquisitions ready for download from Scihub.

AOI Coordinates (bbox)

scihub_acquisition_scraper:develop

3

Multi acquisition localizer (Acquisition Localizer - Multi)

S1-IW_SLC

Based on faceting 'acquisition-S1-IW-SLC', submits spyddder-sling-extract jobs to localize SLCs into ARIA system.

AOI Coordinates (bbox), acquisition-S1-IW-SLC

multi_acquisition_localizer:develop

4

SLCP MRPE (Sentinel-1 MRPE Registered SLC Pair)

S1-SLCP

Based on faceted SLCs, and AOI’s start, event and end times, pair SLCs to form SLCPs based on most recent pre-event scene and submits 'sentinel_rsp-singlescene' jobs.

AOI Coordinates (bbox), S1-IW-SLC, start and end times

ariamh:develop

5

slcp2lar (S1 Log Amplitude Ratio)

S1-LAR

1 SLCP generates 1 LAR. Convert S1-SLCP products to Log Amplitude Ratios (LARs) for creating Flood Proxy Maps v1 (FPMv1).

6

lar2fpm (S1 FPM)

S1-FPM (per subswath)

Based on user’s manual threshold inputs, creates GeoTIFF dataset of flood maps, water-body mask, radar-footprints (burst-wise and sub-swath wise) and log_amps, log_ratio_amps, DEMs (sub-swath wise)

7

FPM packaging (S1 FPM Packaged)

S1-FPM-PKG (Final Product)

Based on user’s facet of S1-FPM (per subswath), stitches S1-FPMs and creates merged Flood Proxy Map in GeoTIFF, ESRI Shapfile and Google Earth KML format.

8

slcp2cod (S1 COD -Network Selector)

S1-COD

2 SLCPs create 1 COD. Based on AOI (aoi_name input), finds intersecting SLCPs and based on AOI event time, pairs pre-event with post-event SLCPs to submit ‘S1-COD’ jobs.

AOI Coordinates (bbox), S1-SLCP

slcp2cod:develop

9

cod2dpm (S1 COD)

S1-DPM (Final Product)

Based on manual facet of S1-CODs and user’s threshold, localizes all S1-COD subswaths, thresholds and stitch them to create merged Damage Proxy Maps in GeoTIFF and Google Earth KML format, rendered in 2 color schemes - `ytr` (normal viewing) and `blu`(colour-blind friendly viewing)

AOI Coordinates (bbox), S1-CODs

cod2dpm:aria-jpl

Will need an additional job that sets up Trigger Rules for the following:

  1. Multi acquisition localizer - for this job to facet on acquisitions intersecting AOI’s coordinates, start and end times.

  2. SLCP MRPE - for this job to facet on SLC based on AOI’s coordinates; and use AOI’s start, event and end times as inputs.

  3. slcp2lar - for this job to facet on any co-event SLCPs to create LARs, based on AOI’s event time.

  4. slcp2cod - for this job to take in AOI’s ID as inputs and specified track number for SLCP pairing to work.

Test Case:

AOI:
