Description
Return total-tree-other+shared and divide by total.
Agroforestry geometry separates row widths, root-zone intervals, canopy projections and repeated-strip area bases. Optical shade, optical porosity and a clear machinery corridor are different quantities. Ideal dimensions and supplied overlaps can support bookkeeping without establishing light conditions, aerodynamic shelter or safe access.
Return total-tree-other+shared and divide by total.
When to use this tool
Use Silvopasture Tree Cover Open Area Share when checking the stated ideal tree-row, shade, buffer or area convention.
How to use the tool and how it works
- Enter totalArea, treeArea, otherExcluded, sharedExcluded. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read openArea, openFraction. Use the output convention below.
Require positive total area, nonnegative tree/other excluded areas and valid shared overlap, with their union within total. Return total-tree-other+shared and divide by total.1
| Input field | Meaning and units | Accepted input |

| totalArea | Total Area | Required. Finite number; strictly above 0. |
| treeArea | Tree Area | Required. Finite number; minimum 0. |
| otherExcluded | Other Excluded | Required. Finite number; minimum 0. |
| sharedExcluded | Shared Excluded | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| openArea | Open Area | Required. Finite number. |
| openFraction | Open Fraction Unit: 1. | Required. Finite number. |

}Limitations and assumptions
- Area unions rely on supplied overlap; no canopy map, forage capacity or animal welfare target is inferred.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use measured terrain and canopy geometry, appropriate light/flow models and qualified agricultural/engineering assessment for actual layouts and operations.
