Description
Interpolate lowHeight to highHeight by distanceFromLow / positive contourDistance, requiring the distance within that span.
Simple site geometry approximates an area, section, or volume using ideal shapes. Coherent length units and the distinction between signed and unsigned quantities determine the result's meaning.
Interpolate lowHeight to highHeight by distanceFromLow / positive contourDistance, requiring the distance within that span.
When to use this tool
Use Landscape Contour Spot Height Interpolation when you need one transparent landscape geometry component.
How to use the tool and how it works
- Enter lowHeight, highHeight, distanceFromLow, contourDistance. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read height. Use the output convention below.

| lowHeight | Low Height | Required. Finite number. |
| highHeight | High Height | Required. Finite number. |
| distanceFromLow | Distance From Low | Required. Finite number; minimum 0. |
| contourDistance | Contour Distance | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| height | Height | Required. Finite number. |

}Limitations and assumptions
- This assumes a linear height profile along the measured line; no terrain model or survey accuracy 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 a surveyed terrain or construction model when irregular shapes, settlement, drainage, and structural performance matter.
