Canopy Height Shoot Length Checker

Project measured upright shoot lengths/inclinations from actual basal heights against caller canopy envelope, not raw length-only comparison or a hedging recommendation.

Description

An inclined shoot's vertical projection is shorter than its measured length.

An inclined shoot's vertical projection is shorter than its measured length. Its basal height also affects the projected canopy top.

Project measured upright shoot lengths/inclinations from actual basal heights against caller canopy envelope, not raw length-only comparison or a hedging recommendation.

When to use Canopy Height Shoot Length Checker

Use this tool to project measured upright shoot lengths/inclinations from actual basal heights against caller canopy envelope, not raw length-only comparison or a hedging recommendation.

Prepare vineyard measurements, dates or block records for the intended growing period. Keep weights, counts and weather observations in the stated units.

How to use Canopy Height Shoot Length Checker and understand its results

Prepare vineyard measurements, dates or block records for the intended growing period. Keep weights, counts and weather observations in the stated units.
Enter measuredShootLengthsM, shootInclinationsFromVerticalDegrees, shootBaseHeightsM, callerAvailableCanopyTopHeightM using the field table and calculation rules, then run the tool.
Read projectedShootTopHeightsM, aboveCallerCanopyTopFlags. 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
measuredShootLengthsM	Measured shoot lengths m	list of number	Required
shootInclinationsFromVerticalDegrees	Shoot inclinations from vertical degrees	list of number	Required
shootBaseHeightsM	Shoot base heights m	list of number	Required
callerAvailableCanopyTopHeightM	Caller available canopy top height m	number	Required

Align nonnegative lengths, basal heights and inclinations in [−90,90] degrees. Flag projected tops strictly above the supplied canopy top; equality is accepted.^[1]

Paired lists must be nonempty and have equal lengths.

projected top = base height + shoot length × cos(inclination)

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

Output field	Meaning	Value type
projectedShootTopHeightsM	Projected shoot top heights m	list of number
aboveCallerCanopyTopFlags	Above caller canopy top flags	list of number

Limitations and assumptions

The geometric screen is not a hedging recommendation.

Numbers and computed results must be finite; overflow produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Hedging Top Height Trimming: Account measured canopy envelope above caller hedge-height scenario across unequal row lengths/widths; rectangular envelope is not actual foliage biomass or a growth-control recommendation. For a complementary task, use Pergola Beam Height Clearance: Audit measured pergola underside minus hanging canopy against caller passage-envelope height, retaining signed margins; no load-bearing, accessibility or worker/equipment safety certification.
