Use this geographic calculation to derive a spherical distance, bearing, destination, or coordinate envelope from well-formed latitude and longitude values.

Start latitude

Latitude of the start point in decimal degrees.

Start longitude

Longitude of the start point in decimal degrees.

Bearing

Initial bearing measured clockwise from true north, in degrees.

Distance (m)

Travel distance along the great circle in meters.

Compute the destination latitude and longitude reached when traveling a given distance from a start point along a fixed initial bearing on a spherical Earth of mean radius 6371008.8 m. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Destination latitude

Latitude of the destination point in decimal degrees.

Destination longitude

Longitude of the destination point in decimal degrees within [-180, 180).

• The result depends on the chosen Earth model and longitude handling. Bounding boxes near the antimeridian or poles and long geodesics need special treatment, and altitude is normally omitted.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result on a map and use ellipsoidal geodesics or a suitable projected CRS when accuracy or area preservation matters.

• Geographic Bounding Box Calculator

  Compute the latitude and unwrapped longitude extents of a radius around a center point on a spherical Earth of mean radius 6371008.8 m. Longitude bounds may fall outside −180° to 180° when the interval crosses the antimeridian.

• Geographic Bearing Calculator

  Calculate the initial forward azimuth in degrees from a start point to an end point on a spherical Earth.

• Haversine Distance Calculator

  Calculate the great-circle distance between two points on a spherical Earth of mean radius 6371008.8 m using the haversine formula.
