Navigation Bearing & AzimuthCartography & GIS
Translate 360-degree azimuth angles to quadrant compass bearings and back-bearings.
Converts quadrant coordinates (e.g. S 45° E) back into Azimuth angles.
Cartographic and geodesic transforms approximate localized ellipsoidal models. Real GIS engines require projection matrices such as NAD83/UTM or local state planes.
