Static Methods
-
havDistance(num lat1, num lat2, num dLng)
→ num
-
Returns hav() of distance from (lat1, lng1) to (lat2, lng2) on the unit
sphere.
-
intersects(num lat1, num lat2, num lng2, num lat3, num lng3, bool geodesic)
→ bool
-
intersects the segment (lat1, lng1) to (lat2, lng2).
Longitudes are offset by -lng1; the implicit lng1 becomes 0.
-
inverseMercator(num y)
→ num
-
Returns latitude from mercator Y.
-
isOnSegmentGC(num lat1, num lng1, num lat2, num lng2, num lat3, num lng3, num havTolerance)
→ bool
-
-
mercator(num lat)
→ num
-
Returns mercator Y corresponding to latitude.

-
sinDeltaBearing(num lat1, num lng1, num lat2, num lng2, num lat3, num lng3)
→ double
