Basic Wood Density Lookup

Audit independently measured dry mass/green-volume basic density reference. 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

Basic wood density uses a specified dry-mass and volume convention.

Basic wood density uses a specified dry-mass and volume convention.^[1]

Species, sampling and moisture basis must match before an observed value and a reference value can be compared. Use this tool to compare an observation with an exact caller-supplied numeric reference.

When to use Basic Wood Density 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 Basic Wood Density Lookup and understand its results

Establish the species/site, survey protocol, units, sampled area or exposure, and the independently chosen reference or model.
Enter callerBasicWoodDensityIds, callerBasicWoodDensityValues, queryBasicWoodDensityId, observedBasicWoodDensityValue, using the field meanings and rules below, then run the tool.
Read callerMatchedBasicWoodDensityValue, signedObservedMinusBasicWoodDensityReference. 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
callerBasicWoodDensityIds	Caller basic wood density ids	list of string	Required
callerBasicWoodDensityValues	Caller basic wood density values	list of number	Required
queryBasicWoodDensityId	Query basic wood density id	string	Required
observedBasicWoodDensityValue	Observed basic wood 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
callerMatchedBasicWoodDensityValue	Caller Matched Basic Wood Density Value; follow the units, sign, ordering and evidence convention stated above	number
signedObservedMinusBasicWoodDensityReference	Signed Observed Minus Basic Wood 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.
