location
open fun locationIndexOnEdgeOrPath(point: LatLng, poly: List<LatLng>, closed: Boolean, geodesic: Boolean, toleranceEarth: Double): Int
Computes whether (and where) a given point lies on or near a polyline, within a specified tolerance. If closed, the closing segment between the last and first points of the polyline is not considered.
Return
-1 if point does not lie on or near the polyline. 0 if point is between poly[0] and poly[1] (inclusive), 1 if between poly[1] and poly[2], ..., poly.size()-2 if between poly[poly.size() - 2] and poly[poly.size() - 1]
Parameters
point
our needle
poly
our haystack
closed
whether the polyline should be considered closed by a segment connecting the last point back to the first one
geodesic
the polyline is composed of great circle segments if geodesic is true, and of Rhumb segments otherwise
tolerance
tolerance (in meters)
