location
fun locationIndexOnPath(point: LatLng, poly: List<LatLng>, geodesic: Boolean, tolerance: Double = DEFAULT_TOLERANCE): Int
Computes whether (and where) a given point lies on or near a polyline, within a specified tolerance. The polyline is not closed -- the closing segment between the first point and the last point is not included.
Return
-1 if point does not lie on or near the polyline. 0 if point is between poly0 and poly1 (inclusive), 1 if between poly1 and poly2, ..., poly.size()-2 if between polypoly.size() - 2 and polypoly.size() - 1
Parameters
point
our needle
poly
our haystack
geodesic
the polyline is composed of great circle segments if geodesic is true, and of Rhumb segments otherwise
tolerance
tolerance (in meters)
