Google Maps Roads Api Returns Duplicate Coordinates And Placeids

I'm implementing google maps roads API to pick up the coordinates where I clicked on the roads. But it returns more than expected coordinates and placeids. Suppose I set a directio

Solution 1:

You are calling the Roads API with interpolate: true. According to the documentation, that causes it to behave the way you say it is.

from the documentation:

• interpolate — Whether to interpolate a path to include all points forming the full road-geometry. When true, additional interpolated points will also be returned, resulting in a path that smoothly follows the geometry of the road, even around corners and through tunnels. Interpolated paths will most likely contain more points than the original path. Defaults to false.
