Bearing & Distance Calculations
Professional surveying bearing tools for coordinate bearings, whole-circle and reduced bearings, back bearings and included angles.
Coordinates to Bearing & Distance
Enter two points to determine ΔE, ΔN, horizontal distance, whole-circle bearing and reduced bearing.
Point A
Point B
Enter Point A and Point B coordinates, then select Calculate.
Bearing + Distance to Coordinates
Calculate the latitude, departure and destination coordinates from a starting point, bearing and distance.
Starting Point
Line Data
Bearing may be entered as decimal degrees (55.512), DMS (55° 30' 42.18") or common DMS notation (55d 30' 42.18").
Enter the starting coordinates, bearing and distance.
Whole-Circle Bearing ↔ Reduced Bearing
Convert bearings between 0°–360° whole-circle notation and quadrantal notation.
Whole-Circle Bearing → Reduced Bearing
—
Reduced Bearing → Whole-Circle Bearing

Back Bearing
Determine the reverse bearing of a survey line. The result is normalized to 0°–360°.
Enter a whole-circle bearing.
Included Angle Between Two Bearings
Calculate the smaller angle between two whole-circle bearings.
Enter two bearings.
