Mapzen Polyline Decoder

Mapzen Mobility products use polylines encoded with a higher level of decimal degree precision (6 digits / ~10cm) than the original encoded polyline format (5 digits / ~1m). Tools that assume 5 digits of precision will return unexpected results. Use this tool to decode Mapzen polylines, and check out our documentation for code samples.
