Description
Return horizontalLength*hypot(1,grade), requiring nonnegative horizontal length.
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 horizontalLength*hypot(1,grade), requiring nonnegative horizontal length.
When to use this tool
Use Tree Row Contour Length Slopefactor when checking the stated ideal tree-row, shade, buffer or area convention.
How to use the tool and how it works
- Enter horizontalLength, grade. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read surfaceLength. Use the output convention below.
Return horizontalLength*hypot(1,grade), requiring nonnegative horizontal length. grade is signed rise/run, not an angle or percentage number.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| horizontalLength | Horizontal Length | Required. Finite number; minimum 0. |
| grade | Signed rise/run as a ratio, not degrees, radians or a percentage number. | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| surfaceLength | Surface Length | Required. Finite number. |

}Limitations and assumptions
- Assumes a straight segment on constant slope; curved contours and terrain variation are not measured.
- 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.
