Nearest API

Snap to Road

Snap any coordinate to the closest point on the real road network. Essential for cleaning GPS input before routing.

Overview

The Nearest API snaps any coordinate to the closest point on the real road network and returns the matched location. It is the building block for cleaning user input before routing, validating pickup/drop-off points, and finding which road a coordinate belongs to. Fast and precise, it underpins reliable routing pipelines.
