I try to create a WordPress plugin, that will use the Google maps directions in combination with bounds.

This is an application for km based charge, that has low cost/km into the bounds and high cost/km outside the bounds.

So the question is:

  1. Is there a way to know what is the distance from within the bounds point to the bounds border
  2. Is there a way to know what is the distance from a point outside the bounds to the bounds borders?

Note that the bounds area will be made with poligons. I have find the way to check if a point in the poligon or outside the poligon.

The problem is what I describe above in the list.

    Yes, there’s a function in the API that measures distances between LatLngs.

    It’s called : computeLength() in the geometry library.

    Please read this

    Distance and Area Functions

    The distance between two points is the length of the shortest path between them. This shortest path is called a geodesic. On a sphere all geodesics are segments of a great circle. To compute this distance, call computeDistanceBetween(), passing it two LatLng objects.

    You may instead use computeLength() to calculate the length of a given path if you have several locations.

    Distance results are expressed in meters.

    To compute the area (in square meters) of a polygonal area, call computeArea(), passing the array of LatLng objects defining a closed loop.
