- Compass point between two locations
Given coordinates of two locations in decimal degrees, this calculator displays constant azimuth, distance and compass points for different compass roses.
- Points of the compass
This online calculator outputs compass point given direction angle in degrees. Different compass roses (4, 8, 16, 32, 128-wind compass roses) are supported.
- City objects observation
The calculator helps to distinguish observed city objects.
- Compass Points
The calculator gives name of compass point by direction angle in degrees.
- Compass, magnetic and true course.
Calculates true, magnetic and compass direction(course, bearing) by given direction, magnetic declination and deviation.
- Course angle and the distance between the two points on loxodrome (rhumb line).
Calculation of a distance on loxodrome (rhumb line) and course angle (azimuth) between two points with a given geographical coordinates.
- Course angles and distance between the two point on the orthodrome(great circle)
Calculates the distance between two point of the Earth specified geodesic (geographical) coordinates along the shortest path - the great circle (orthodrome). Calculates the initial and final course angles and azimuth at intermediate points between the two given.
- Distance across the surface vs distance through the Earth
This calculator calculates distance across the surface of the Earth and distance through the Earth for given two points, then compares them.
- Distance through the Earth
This calculator calculates the distance from one point on the Earth to another point, going through the Earth, instead of going across the surface.
