Get Distance Between Specific Point to the Line Drawn on Google Map
ikhsanudinhakim
I have a point (lat, lng) X and a route drawn on the google map as shown below.
In my app, I have a rule:
If the distance between point X to the nearest point that is passed by the route is less than 5 meters, then the route can be traversed.
Otherwise, if the distance between points X to the closest point passed by the route is equal to or greater than 5 meters, then the route cannot be traversed.
Is this rule can be applied by using google map service?

The Google Maps Javascript API has a Geometry library.
The Geometry library has a isLocationOnEdge function. See the documentation.
To determine whether a point falls on or near a polyline, or on or near the edge of a polygon, pass the point, the polyline/polygon, and optionally a tolerance value in degrees to
google.maps.geometry.poly.isLocationOnEdge(). The function returns true if the distance between the point and the closest point on the line or edge falls within the specified tolerance. The default tolerance value is 10-9 degrees.
