How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula
D3 = √(dh² + Δh²)Inputs
| Name | Unit |
|---|---|
| Horizontal distance | m |
| Elevation 1 | m |
| Elevation 2 | m |
Outputs
| Name | Unit |

Diagnose
This tool does not attach diagnose observations.
Assumptions
- Horizontal distance is already the plan distance between the points.
Provenance
- Local Euclidean. Not a geodetic 3D chord through the ellipsoid.
