Fields | Description | Type | Example |
---|---|---|---|
| Suffix dataset tag to append at the end of the dataset id for differentiating events or settings | string |
|
| Project category for possible queue propagation later | enum |
|
| SLCP version to pair CODs for. Default is | string |
|
| Dataset ID of AOI to find SLCPs for CODs creation based on AOI's coordinates, start, end and event time | string |
|
| Optional) Specific track number (only one allowed) of SLCPs overlapping AOI to process CODs for. If not specified, creates CODs for all tracks overlapping AOI. | int |
|
| (Optional) Range looks to override SLCP's range looks to create CODs in the format: subswath1, subswath2, subswath3. If not specified, uses the range looks stored in SLCP for all subswaths. | int,int,int |
(Recommended defaults) |
| (Optional) Azimuth looks to override SLCP's range looks to create CODs in the format: subswath1, subswath2, subswath3. If not specified, uses the azimuth looks stored in SLCP for all subswaths. | int,int,int |
(Recommended defaults) |
| Minimum number of CODs to created. Priority of creation is based on temporal baseline. (See Notes below) | int |
(Recommended defaults) |
| Minimum ratio of overlap between pre-event_SLCP and co-event_SLCP. Should be < 1. (See Notes below) | float |
(Recommended defaults) |
Important outputs:
No products will be directly generated, only S1-COD jobs will be submitted based on pairing results. (Expect 1 job for each subswath)
Notes:
The COD network selector pairs SLCPs to submit to the
S1-COD
job based on the following workflow:Gather
pre-event_SLCPs
+co-event_SLCPs
from GRQ. Search criteria:SLCPs are pre-event if
SLCP_end_time < AOI_event_time
SLCPs are co-event if
SLCP_start_time < AOI_event_time < SLCP_end_time
Match pre-event_SLCP and co-event_SLCP pairs if:
pre-event_SLCP[‘master_time’] - co-event_SLCP[‘master_time’] < 1 day
area_intersect(pre-event_SLCP,co-event_SLCP) / area(co-event_SLCP) > min_overlap
Creates and returns
minmatch
or valid SLCP pairs for COD based on shortest temporal baseline, wheretemporal baseline =
co-event_SLC['slave_time'] - pre-event_SLCP['slave_time']
Hence, if there are multiple pre-event SLCPs as per the following:
If
minmatch
= 1, only COD 1's job will be submittedIf
minmatch
= 2, both COD 2 and COD 1 will be submitted

Notes:
The CODs in this PGE are computed as such (from
burst_coherence_diff.py
):
where COR = Coherence of given co-registered SLCP
