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.
Description
A canopy envelope represents geometric space rather than foliage biomass.
A canopy envelope represents geometric space rather than foliage biomass. Comparing its top with a hedge scenario estimates the space above that line.
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.
When to use Hedging Top Height Trimming
Use this tool to 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.
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 Hedging Top Height Trimming 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 observedCanopyTopHeightsM, callerHedgeTopHeightsM, canopyBottomHeightsM, canopyWidthsM, representedRowLengthsM using the field table and calculation rules, then run the tool.
- Read topHeightAboveCallerHedgeM, rectangularEnvelopeVolumeAboveCallerHedgeM3. 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 |
|---|---|---|---|
| observedCanopyTopHeightsM | Observed canopy top heights m | list of number | Required |
| callerHedgeTopHeightsM | Caller hedge top heights m | list of number | Required |
| canopyBottomHeightsM | Canopy bottom heights m | list of number | Required |
| canopyWidthsM | Canopy widths m | list of number | Required |
| representedRowLengthsM | Represented row lengths m | list of number | Required |
Align heights, nonnegative widths and positive row lengths. Require observed and hedge tops at or above canopy bottoms. Return local height excesses and rectangular excess m³.1
Paired lists must be nonempty and have equal lengths.
excess envelope = Σ max(0,observed top − hedge top) × width × represented length Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| topHeightAboveCallerHedgeM | Top height above caller hedge m | list of number |
| rectangularEnvelopeVolumeAboveCallerHedgeM3 | Rectangular envelope volume above caller hedge m3 | number |

}Limitations and assumptions
The envelope is not biomass removal or a growth-control 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 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. For a complementary task, use Canopy Width Vigour Classification Tool: Audit physical canopy widths by represented row length against caller local/pooled width bands; width alone does not establish physiological vigor or treatment need.
