How this service works
Snap GPS coordinates to roads
Output
Returns a list of snapped road points, each with corrected latitude/longitude coordinates aligned to the nearest road, along with optional place IDs for road segments and interpolated points that were added to fill gaps in the path.
Example use cases
Example prompt
“I have a series of raw GPS coordinates from a drive — 37.4229,−122.0840 then 37.4231,−122.0845 then 37.4235,−122.0850 — can you snap them to the nearest roads so the path lines up properly with the road network?”
Technical details
Endpoint
GEThttps://googlemaps.mpp.tempo.xyz/roads/v1/snapToRoads?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have raw GPS traces from vehicles or devices and need to align them to the road network — ideal for route reconstruction, fleet tracking visualization, map-matching for navigation apps, or cleaning noisy GPS data. Prefer this over manual interpolation or other road-snapping services when accuracy against Google's road graph is required.
Side effects
- Invalid or out-of-range coordinates return an error
- Too many input points exceeding API limit causes rejection
- Points in areas without road data may not snap accurately
- Missing path parameter returns 400 bad request
- Network timeout for large coordinate sets
- Coordinates far from any road may produce unexpected snapping results
