Description
Subtract firstContour from secondContour with exact integer intermediates and multiply by positive contourInterval for heightDifference.
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.
Subtract firstContour from secondContour with exact integer intermediates and multiply by positive contourInterval for heightDifference.
When to use this tool
Use Site Contour Height Step when you need one transparent landscape geometry component.
How to use the tool and how it works
- Enter firstContour, secondContour, contourInterval. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read heightDifference. Use the output convention below.

| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstContour | First Contour | Required. Safe integer. |
| secondContour | Second Contour | Required. Safe integer. |
| contourInterval | Contour Interval | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| heightDifference | Height Difference | Required. Finite number. |

}Limitations and assumptions
- Contour numbering and vertical interval are supplied; terrain between contours and survey accuracy are not 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.
