Updated location code 42 on NZA, NZB, NZC, and NZE to match the data from the BPRs.

Timestamps
NZA: 2023-12-15T22:00:00Z,2025-12-16T21:59:45Z
NZB: 2023-12-06T15:00:00Z, current (end of file was corrupted)
NZC: 2023-12-08T23:00:00Z,2025-12-07T22:59:45Z

"NZB: 2023-12-06T15:00:00Z, current (end of file was corrupted)"
Is there a way to document "the absence of data" -as we re going to forget this corrupted file in few years
?

Delta installs should reflect the times of potential data, rather than actual data. This is to avoid becoming a holdings database.

There might be a chance data is recovered, or that it was collected in real time.

To address issues related to usability we tend to work with streams. That is the bpr derived streams may reflect what was recovered, but the gauge installations reflect ship logs or visit times etc.

This is to avoid questions about gaps.

I'm a little confused, should any changes be made to this PR then?

For NZE the last data is to me 2025-12-10T20:59:45Z 107.64786 9.01079 72.124 so 72 meters as i can see
Check the BPR dates again to find the most sensible data at least on that one.

@EvanCGNS
dates are okay for NZA, NZC
Last data for the BPR NZB "raw" is 2025/10/25 16:00 ( we can discuss if this stands somewhere relevant)
It looks like you took only dates for the last data time almost that but not for NZE
cheers

[salichon]

and for NZB @EvanCGNS
Let s base our time assumption on
"There might be a chance data is recovered, or that it was collected in real time."
as Mark mentioned indeed.
so time NZB is relevant enough,

Good spotting @salichon about NZE. I have 2025-12-10T18:54:15Z as the ending timestamp now, I'll update the PR

[EvanCGNS]

@salichon and @ozym the PR is ready for re-review
