About Thyseus
Thyseus is a community-powered platform for GPS coordinate mapping of objects across the United States. By combining public traffic camera feeds, in-browser vehicle detection, and calibrated camera geometry, it places cars, motorcycles, buses and trucks on a live map in near real time.
What is community-powered GPS coordinate mapping?
It is a crowdsourced approach where anyone can help map precise GPS coordinates of objects using camera feeds and shared observations, creating an open geospatial dataset.
Is Thyseus available across the United States?
Yes. Thyseus focuses on GPS coordinate mapping of objects across the United States, and can extend globally where camera feeds and contributors are available.
How does Thyseus estimate GPS coordinates from cameras?
Thyseus calibrates each camera's geometry: where it stands, how high it is mounted, how steeply it looks down, and which way it points. When the detector in your browser finds a vehicle, its position in the frame is projected from that single camera onto the road and converted to GPS coordinates.
What are common use cases?
Popular use cases include public safety awareness, traffic and roadway analytics, infrastructure monitoring, and mapping points of interest for research and civic projects.
How can I contribute?
Open the live map and pick a camera: detection runs in your browser, and on calibrated cameras the vehicles it finds appear on the map for everyone watching. Signed in, your detections count toward the leaderboard and you can vote on whether a camera's placement looks right.
What about privacy?
Thyseus focuses on mapping objects and infrastructure, not individuals. We prioritize public sources, aggregate insights, and implement safeguards to reduce personal identification.
