Stand Table Lookup
Audit caller diameter-class stand inventory table. Audit caller independently verified matched reference against actual observation, not a fabricated specification. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.
Description
Stand-density indices depend on the chosen diameter basis and reference relationship.
Stand-density indices depend on the chosen diameter basis and reference relationship.1
A supplied index record must match the observed stand convention before the signed difference has meaning. Use this tool to compare an observation with an exact caller-supplied numeric reference.
When to use Stand Table Lookup
Use this tool to compare an observation with an exact caller-supplied numeric reference. Establish the species/site, survey protocol, units, sampled area or exposure, and the independently chosen reference or model.
How to use Stand Table Lookup and understand its results
- Establish the species/site, survey protocol, units, sampled area or exposure, and the independently chosen reference or model.
- Enter callerStandClassDensityIds, callerStandClassDensityValues, queryStandClassDensityId, observedStandClassDensityValue, using the field meanings and rules below, then run the tool.
- Read callerMatchedStandClassDensityValue, signedObservedMinusStandClassDensityReference. Interpret the fields using their units, signs and evidence conventions below.
- If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerStandClassDensityIds | Caller stand class density ids | list of string | Required |
| callerStandClassDensityValues | Caller stand class density values | list of number | Required |
| queryStandClassDensityId | Query stand class density id | string | Required |
| observedStandClassDensityValue | Observed stand class density value | number | Required |
Enter nonempty aligned caller reference IDs and numeric reference values, an exact query ID and an observed value on the same unit and protocol basis. Reference values and the observation must be nonnegative; they need not be integers. IDs must be unique and nonblank, with at most 128 UTF-16 units each. The implementation uses case-sensitive exact matching without trimming, returns the matched reference value and subtracts it from the observation. An absent query or duplicate key fails. No regional dataset is installed, retrieved or authenticated.
reference=values[indexOfExact(queryId,ids)]; signedDifference=observed−reference Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| callerMatchedStandClassDensityValue | Caller Matched Stand Class Density Value; follow the units, sign, ordering and evidence convention stated above | number |
| signedObservedMinusStandClassDensityReference | Signed Observed Minus Stand Class Density Reference; follow the units, sign, ordering and evidence convention stated above | number |

}Limitations and assumptions
The numerical reference, unit basis and observation come from the caller. No authoritative regional table, standard edition, calibration or management rule is installed, retrieved or verified.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
