Vehicle tracker

The Vehicle tracker layer shows moving vehicles or assets live on the map. It's designed for fleet, transit, and asset-tracking scenarios where positions update over time.

Live position sources

Vehicle positions can come from:

  • A GTFS-Realtime feed (the standard for public-transport vehicle positions), or
  • A custom JSON feed or a data source with an auto-refresh interval.

An optional GTFS static timetable adds stop names and route colors.

What it shows

  • Live markers for each vehicle, which can be simple symbols or 3D models.
  • Trails showing where each vehicle has been.
  • Smooth animation between position updates so movement reads naturally.
  • Track snapping — vehicles can be snapped to GTFS shapes, the road network, or rail lines so they follow real routes rather than jumping in straight lines.
