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. See http://en.wikipedia.org/wiki/Mercator_projection .

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

Constants

EARTH_RADIUS → const double
