Determines the clockwise angle deviation from the North direction.
The implementation uses the Rhumb line algorithm which is efficient and accurate for short distances.
$ npm install --save angle-deviation-from-north
const determineAngleDeviationFromNorth = require('angle-deviation-from-north');
const from = { latitude: 59.45337, longitude: 18.5579 };
const to = { latitude: 59.45337, longitude: 18.5569 };
determineAngleDeviationFromNorth(from, to);
//=> 270Gives the heading of the line from one position to another.
For example, if you draw an arrow from fromPosition to toPosition then the arrow will have the heading returned by this function.
The returned angle is in degrees and can be [0.0, 360.0), greater than or equal 0 and less than 360.
The two positions must have the properties latitude and longitude.
