Snap to Roads - Amazon Location Service

Snap to Roads

The Snap to Road API enhances the accuracy of geographic positioning by aligning GPS coordinates to the nearest road segments on a digital map. This API takes raw longitude and latitude data, often collected from mobile devices or vehicles, and "snaps" these points to the corresponding road network, correcting inaccuracies caused by GPS drift or signal loss. By integrating the Snap to Road API, developers can ensure their applications provide reliable and accurate data, supporting better decision-making and operational efficiency across various scenarios.

Use cases

  • Enhance navigation accuracy by snapping to the road network: Efficiently align GPS coordinates to the nearest road segments to improve navigation accuracy. This feature is valuable for mapping and navigation services, providing users with precise directions and real-time location updates, thus enhancing the navigation experience.

  • Improve data accuracy for fleet management applications: Correct the reported positions of vehicles by snapping their GPS coordinates to the closest roadways. In fleet management systems, this feature ensures accurate vehicle tracking, enabling optimized logistics and better operational efficiency.

Understand the request

The request requires TracePoints to match to roads, with optional parameters like SnappedGeometryFormat and SnapRadius for controlling geometry format and snapping radius. .

TracePoints

A list of coordinates to be snapped to the road network.

SnappedGeometryFormat

The format of the returned geometry, such as "FlexiblePolyline" or "Simple".

SnapRadius

The radius around trace points within which road snapping is considered.

Understand the response

The response contains corrected geometry and snapped trace points, with properties like SnappedGeometry and SnappedTracePoints to indicate accuracy and snapping confidence. .

SnappedGeometry

The corrected geometry of the snapped route.

SnappedTracePoints

The adjusted coordinates of the trace points snapped to roads.

Notices

Warnings or informational messages about the snapping process.
