Grid Reference to Survey Coordinate Converter
Exact caller independently verified Grid Reference to Survey Coordinate Converter reference lookup. Required actual context: actual grid system/CRSzone, datum, coordinate origin, units and independently verified cave survey transform; not anonymous grid string to physical coordinates. Illustrative records are not authoritative data. No universal material coefficient, law, norm, medical limit, diagnosis, clinical dose, work-safety approval, engineering design or guaranteed forecast is inferred. This operation retrieves actual qualified reference text; it does not calculate a missing physical model or verify the truth of supplied evidence.
Description
A grid reference belongs to a coordinate system, zone, datum and origin.
A grid reference belongs to a coordinate system, zone, datum and origin.1
An applicable transformation record is different from a coordinate conversion inferred from an anonymous string.
When to use Grid Reference to Survey Coordinate Converter
Use this tool to retrieve a recorded reference with its source context. Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.
How to use Grid Reference to Survey Coordinate Converter and understand its results
- Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.
- Enter callerVerifiedSource, callerVerifiedContext, callerVerifiedAsOfDate, callerReferenceKeys, callerReferenceTexts, queryReferenceKey, using the field meanings and rules below, then run the tool.
- Read matchedCallerReference with source, context and asOfDate. Confirm independently that this supplied record applies to your actual case.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerVerifiedSource | Caller verified source; supplied assertion retained unchanged, not independently verified | string | Required |
| callerVerifiedContext | Caller verified context; supplied assertion retained unchanged, not independently verified | string | Required |
| callerVerifiedAsOfDate | Caller verified as of date; real Gregorian YYYY-MM-DD date for the supplied record | string | Required |
| callerReferenceKeys | Caller reference keys | list of string | Required |
| callerReferenceTexts | Caller reference texts | list of string | Required |
| queryReferenceKey | Query reference key; use the exact reference token or coordinate domain stated below | string | Required |
Supply nonempty aligned unique nonblank reference keys and nonblank texts, then query one exact existing key. Matching is case-sensitive without trimming or normalization. Return the matched text and the supplied source, context and as-of date unchanged. Source and context must be nonblank, at most 1024 units of UTF-16 each; the date must be a real Gregorian YYYY-MM-DD in years 0001..9999. These provenance fields are caller assertions, not independent verification. Unknown keys fail.
result={matchedCallerReference:texts[indexOf(keys,exactQuery)],source,context,asOfDate} Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Qualified observed calculation or explicit reference | object |
| result.matchedCallerReference | Original caller reference text matching the exact query key. | string |
| result.source | Caller-supplied reference source string, returned unchanged. | string |
| result.context | Caller-supplied reference applicability context, returned unchanged. | string |
| result.asOfDate | Caller-supplied record date, returned unchanged; it does not prove verification. | string |

}Limitations and assumptions
The actual observation coverage, calibration and qualified plan determine applicability. A numerical result does not establish survey accuracy, route suitability, atmosphere conditions or equipment adequacy beyond the declared comparison. Reference records and their claimed verification are supplied by the caller; the tool does not retrieve or verify them.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. String lists allow at most 128 entries of at most 128 UTF-16 units each; blank and duplicate rules are stated above. Extremely large composite outputs are rejected.
