Spherical geometry utility class for WME (Waze Map Editor) userscripts.
Provides geodesic calculations on a spherical Earth model: bearings, angles, Haversine distances, destination points, and great-circle intersections. All coordinates use [longitude, latitude] order in degrees.
Load via @require in a userscript header:
// @require https://greasyfork.org/scripts/.../GeoUtils.user.js
Then use the global GeoUtils class:
const bearing = GeoUtils.getBearing([30.52, 50.45], [-0.13, 51.51]);
const distance = GeoUtils.getDistance([30.52, 50.45], [-0.13, 51.51]);
| Method | Description |
|---|---|
getBearing(pA, pB) |
Initial bearing from pA to pB (0-360) |
findAngle(p1, p2, p3) |
Interior angle at vertex p2 (0-180) |
getDistance(pA, pB) |
Distance in meters (Haversine) |
getAngularDistance(pA, pB) |
Distance in radians |
getDestination(point, bearing, distRad) |
Point at given bearing and angular distance |
findIntersection(pA, pB, pC, angle) |
Point on line AB making given angle with C |
findRightAngleIntersection(pA, pB, pC) |
Perpendicular foot from C onto line AB |
