Geolocation systems

VPS (Google & Apple)

Enjoy ultra-precise visual positioning in all areas covered by panoramic imagery—that is, virtually the entire French territory, particularly along roads and in urban centers.

RTK

RTK technology offers centimeter-level accuracy across the entire French territory.

To use this feature, you must have an RTK unit (For more information, see Le GNSS RTK)

Automatic Routes

Sonarvision automatically guides you through cities where pedestrian mapping is available.

• Available today in Paris, Lyon, and Angers.

• Also available in all areas with detailed pedestrian mapping on OpenStreetMap.

• New cities are regularly added to expand coverage.

GNSS RTK

Centipede Network Availability

The Centipede network, which enables the use of RTK, covers most of metropolitan France, certain overseas territories, and a few other regions around the world. The SonarVision app automatically connects to the nearest active RTK base station.

You can visit the official card to view existing stations worldwide.

The publishing platform

The app.sonarvision.fr editing platform

The editing tools for manually modifying a route are available worldwide! However, the route calculator and base maps, which rely on highly accurate cartographic data, are not available everywhere.

The route planner

For now, our route planner is only available in mainland France.

We are working on a route planner that works worldwide.

However, routes will only follow pedestrian paths (sidewalks, crosswalks, stairs, etc.) if this data exists on OpenStreetMap.

Here's a map Allowing you to view pedestrian data on OpenStreetMap.

Base maps

Base maps are crucial for planning your routes. We recommend scrolling through the different base maps to determine which one is most accurate for you.

There is often a trade-off between image accuracy and the date the images were taken.

Try comparing aerial imagery with recent panoramic imagery or by visiting the location in person.

• In France, we recommend starting with the France Satellite UHD and HD tilesets.

• The France Express 2024 base map contains the most recent imagery, but is less accurate and does not cover all of France.

• The Mapbox base map covers the entire world in principle, but is not always the most accurate or the most recent.

• The OpenStreetMap basemap should be used with caution, as building outlines are often based on cadastral data and are accurate to within about ten centimeters.
