• Convert your coordinates into… Everything is working fine but the bearing doesn't quite work right yet. I have a list of locations with corresponding lat/long coordinates and am trying to calculate initial bearings between two locations. The first calculates a distance on loxodrome (rhumb line) and course angle (azimuth) between two points with given geographical coordinates. Distance and bearing may be taken from topographical maps for quick analyses but great circle calculations are needed for more accurate work and are described here. I'm trying to calculate a bearing (degrees, distance) between two points, a and b. Enjoy!

This online calculator is created after the user's request, and it is just a convenient shortcut between Course angle and the distance between the two points on loxodrome (rhumb line). • Calculate the midpoint between two coordinates. The distance formula is used to determine the distance, d, between two points. If the coordinates of the two points are (x 1, y 1) and (x 2, y 2), the distance equals the square root of x 2 − x 1 squared + y 2 − y 1 squared. The distance formula is derived by creating a triangle and using the Pythagorean theorem to find the length of the hypotenuse. Edit. Found inside – Page 197Calculate the necessary length and bearing of FC . [ Ans .
