Functions

Name	Description
closestPointOnLineFromPoint (LatLon p1, LatLon p2, LatLon point)	Calculates the closest point on the line A to B from the point given. Arguments p1 (LatLon) - The latitude-longitude coordinates of the start point of the line. p2 (LatLon) - The latitude-longitude coordinates of the end point of the line. point (LatLon) - The latitude-longitude coordinates to measure distance from. Returns LatLon - The closest LatLon.
closestPointOnSetOfLines (LatLons latlons, LatLon latlon)	Calculates the closest point on a set of lines from the LatLon given. Arguments latlons (LatLons) - The LatLon coordinates of the lines. latlon (LatLon) - The latitude-longitude coordinates to measure distance from. Returns LatLon - The closest LatLon.
convexPolygonsIntersect (Array polygon1, Array polygon2)	Tests if two convex polygons are intersecting. Arguments polygon1 (Array) - An array of Point representing a polygon. The array must be ordered so that two consecutive values represent an edge of the polygon. polygon2 (Array) - An array of Point representing a polygon. The array must be ordered so that two consecutive values represent an edge of the polygon. Returns Boolean - True if the polygons intersect and false otherwise.
findDistanceToEndOfPath (LatLons path)	Calculates the distance to the end of a path. Arguments path (LatLons) - The LatLon coordinates of the lines. Returns Number - The calculated distance in meters.
pointInsideConvexPolygon (Point point, Array polygon)	Tests if a point is inside the bounds of a polygon. On the edge of the polygon is considered inside. Arguments point (Point) - The test point. polygon (Array) - An array of Point representing a polygon. The array must be ordered so that two consecutive values represent an edge of the polygon. Returns Boolean - True if the point is inside the polygon and false otherwise.
