location
open fun locationIndexOnPath(point: LatLng, poly: List<LatLng>, geodesic: Boolean, tolerance: Double): 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 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
geodesic
the polyline is composed of great circle segments if geodesic is true, and of Rhumb segments otherwise
tolerance
tolerance (in meters)
