Description
Label a tide observation's recorded low/high or changing phase.
Nautical quantities require explicit north, datum, sign, station and unit conventions. A wrapped bearing error has a chosen opposite-direction endpoint, while a circular sector has its own start and end policy. Supplied polar speeds, tank factors and tide labels are references rather than verified navigation or vessel conditions.
Label a tide observation's recorded low/high or changing phase.
When to use this tool
Use Tide Observation Low High Phase Token when you already have recordId, reportedPhase and need to label a tide observation's recorded low/high or changing phase.
How to use the tool and how it works
- Enter recordId, reportedPhase. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read label. Use the output convention below.
Require recordId nonempty and an allowed reportedPhase; format ID [phase].1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| recordId | Record Id | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| reportedPhase | Reported Phase | Required. Text; one of "low", "rising", "high", "falling", "unspecified"; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| label | Label | Required. Text; maximum UTF-16 length 8192. |

"input": {
"recordId": "T17",
"reportedPhase": "rising"
},
"output": {
"label": "T17 [rising]"
}
}Limitations and assumptions
- No tide is predicted, measured or verified and no safe transit window is inferred.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Use verified charts, observations, vessel documentation and the complete relevant geometric or hydrostatic model for a navigational question. Preserve the local bearing/datum convention and treat scalar factors or sector checks as limited inputs rather than operational decisions.
