Grading Size Class Lookup

Audit actual plant-size annotations against explicit caller lower-inclusive grading bands, retaining unobserved size separately; no official plant grade or suitability inference.

Description

Plant grading requires an explicit size-band scheme and observed size evidence.

Plant grading requires an explicit size-band scheme and observed size evidence. Lower-inclusive edges determine exact-boundary assignments.^[1]

Enter aligned nonempty unique class IDs/nonnegative strictly increasing lower edges starting at zero and aligned nonempty nonnegative sizes/binary evidence. Return indices, known counts and unknown count.

When to use Grading Size Class Lookup

Use Grading Size Class Lookup when you need to evaluate the supplied records under the calculation and evidence rules below. No official grade, missing-size inference or suitability classification is supplied.

Prepare the measured crop, container, lighting or inventory records requested. Supply verified local catalogs, calibration factors and crop-stage limits; keep units and dates consistent.

How to use Grading Size Class Lookup and understand its results

Prepare the measured crop, container, lighting or inventory records requested. Supply verified local catalogs, calibration factors and crop-stage limits; keep units and dates consistent.
Enter callerSizeClassIds, callerSizeClassLowerEdgesCm, observedPlantSizesCm, sizeObservationFlags using the field table and calculation rules, then run the tool.
Read callerObservedSizeClassIndices, knownClassCounts, unknownSizeCount. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
callerSizeClassIds	Caller size class ids	list of string	Required
callerSizeClassLowerEdgesCm	Caller size class lower edges cm	list of number	Required
observedPlantSizesCm	Observed plant sizes cm	list of number	Required
sizeObservationFlags	Size observation flags	list of number	Required

class=greatest edge≤size if known; otherwise −1

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
callerObservedSizeClassIndices	Caller observed size class indices	list of number
knownClassCounts	Known class counts	list of number
unknownSizeCount	Unknown size count	number

Limitations and assumptions

No official grade, missing-size inference or suitability classification is supplied.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Caliper To Ball Size Lookup: A caliper-based root-ball schedule needs explicit lower-inclusive bands. The observed stem size selects its required ball diameter. For a complementary task, use Balled Burlap Ball Diameter Spec Lookup: A verified tree specification can define separate root-ball diameter and depth requirements. Both margins matter to the local check.
