Point From Two Bearings

Local easting/northing intersection of two compass bearings (0° = north, 90° = east). Forward rays only.

App id: GEO-10. Reference version 1.0.

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

P = A + t·(sinθ, cosθ)

Inputs

Name	Unit
Easting A	`m`
Northing A	`m`
Bearing A → unknown	`deg`
Easting B	`m`
Northing B	`m`
Bearing B → unknown	`deg`

Outputs

Name	Unit
Easting (hero result)	`m`
Northing	`m`
Distance from A	`m`
Distance from B	`m`

Diagnose

This tool does not attach diagnose observations.

Assumptions

Bearings are compass azimuths, not math angles from east.

Provenance

Local tangent-plane. Rejects parallel bearings and intersections behind either observer.
