Polygon / Bearing Calculator

Click grid to add points. Fill Start / End or use bearing + distance (DMS).
Start (X, Y) Starting point
End (X, Y) Ending point
Bearing → Coordinate Enter DMS
If decimal degrees are entered only, system will use that value (ignoring min/sec).

How to Use:

  1. Calculate Bearing: Enter start (Start X,Y) and end (End X,Y) coordinates, then click "Calculate Bearing".
  2. Calculate Coordinate: Enter start coordinates (Start X,Y), bearing (in DMS), and distance, then click "Calculate Coordinate".
  3. Add Point: Click on grid to add new point or use "Add to grid" button after calculating coordinates.
  4. Navigation:
    • Click & Seret (Drag) to pan.
    • Click to add point.
  5. Set Start Point: Click "Set from point" to use the last point as start point.
  6. Snap to Grid: Click "Snap" to round coordinates to nearest grid.
  7. Export Data: Click "Export CSV" to download all points.

Format Bearing:

Bearing is measured from North (0°) clockwise. Formats:

  • DMS (Degree, Minute, Second)
  • Decimal (e.g., 45.5°)
