Turn GPS Data into Precise Routes
Transform noisy GPS traces into accurate routes aligned to the road network. Perfect for analyzing historical location data and visualizing actual paths taken.
MapAtlas Map Matching API converts noisy GPS coordinates into precise routes aligned to the road network. Our algorithm corrects GPS inaccuracies, removes outliers, and snaps positions to the actual roads traveled.
Every matched segment includes a confidence score indicating match quality. Low scores highlight areas with GPS signal loss or ambiguous road networks, helping you identify and handle data quality issues effectively.
