IndoorAtlas vs TomTom

IndoorAtlas uses patented geomagnetic fusion technology that maps the Earth's magnetic field patterns inside buildings through a process called magnetic fingerprinting. The technology combines magnetometer data with other sensors like WiFi and Bluetooth for robust positioning.

Setup requires fingerprinting the venue by systematically walking through all corridors and spaces to build a magnetic map. The platform then identifies problematic areas through red (conflicting data), blue (insufficient coverage), and path orientation errors that require correction before the map is production-ready.

IndoorAtlas offers production subscriptions starting at 349 euros per month per venue, with a development plan at 400 euros per month. A free tier is available for developers to start building.

IndoorAtlas claims industry-leading accuracy down to 50 centimeters using its 6-layer sensor fusion core across diverse environments, though accuracy varies based on building magnetic patterns and requires careful calibration.
