This process may work if the road is straight, but often results in the interpolated point being placed at a distance offset from the road network on curved sections. -The search uses a more advanced process that considers the actual shape of the street when locating a point without a matching address. This results in more accurate location estimation because the interpolated addresses points are placed on the road itself, which also makes it easier for routing and turn-by-turn navigation services to calculate directions for that location. +To improve upon the straight line technique, the Mapzen Search interpolation implementation considers the actual shape of the street when locating a point without a matching address. This results in more accurate location estimation because the interpolated addresses points are placed on the road itself, which also makes it easier for routing and turn-by-turn navigation services to calculate directions for that location. If the address was derived using this technique, you see `interpolated` for the `match_type`.
