Functions

computeDistanceBetween(LatLng p1, LatLng p2, {num radius = earthRadius}) → num

Compute distance between 2 points.

computeDistanceEquirectangularApproximation(LatLng p1, LatLng p2, {num radius = earthRadius}) → num

Compute distance between 2 points by using Pythagorean theorem on an equi­rectangular projec­tion.

computeDistanceHaversine(LatLng p1, LatLng p2, {num radius = earthRadius}) → num

Compute distance between 2 points according to Haversine formula.

computeDistanceSphericalLawCosines(LatLng p1, LatLng p2, {num radius = earthRadius}) → num

Compute distance between 2 points according to Spherical law of cosines.

computeHeading(LatLng p1, LatLng p2) → num

Compute heading from p1 to p2. The result is between -180 exclusive and 180 inclusive.

computeOffset(LatLng origin, num distance, num heading, {num radius = earthRadius}) → LatLng

Compute the LatLng resulting from moving a distance (in meters) from origin in the specified heading (expressed in degrees clockwise from north).

degToRad(num deg) → num

Convert degrees to radians

radToDeg(num rad) → num

Convert radians to degrees
