What can you do with Cematlas?
A free atlas for exploring major transport infrastructure around the world. Here is what the site actually provides.
85 catalogued cities
US airport traffic events (FAA)
US airports offer active FAA ground stops, delay programs and restrictions. The notices do not provide individual flight statuses.
Explore →Airport weather observations
Airport pages with ICAO codes can display recent METAR observations (temperature, wind and aviation weather category) on request, sourced from the Aviation Weather Center. These are not live flight statuses.
Explore →OpenStreetMap
Explore interactive maps of airports, train stations, metro networks, ports and cities. Some metro network coordinates are approximate.
Explore →Airports · Stations · Metros · Ports
Open place profiles, look up cities and IATA/ICAO codes, and open 360° panoramas, satellite images and Google Earth 3D on external services, where available. Airport pages also link to transit and driving directions. Indoor views are not guaranteed.
Explore →Transport news
Read recent aviation, rail and maritime headlines; filter or search by location. French machine translations are offered where available and may contain errors. The source, date and original article remain accessible.
Explore →Compare routes between two cities
Select two cities, compare their catalogued stations, airports, metros and ports, then open directions in Google Maps. No invented prices or schedules.
Explore →City travel planning and SNCF notices
City pages combine transport hubs, route planning and, for French cities, national SNCF notices from an official public GTFS-RT feed. Notices may not relate specifically to that city.
Explore →Traveler community
Share city-specific transport, accommodation and sightseeing tips. Posts are moderated before publication.
Explore →Search assistant
Ask the Cematlas Assistant to find places and codes in your browser's catalogue. It is not a generative AI and cannot provide verified live updates.
Explore →Limits and privacy
Cematlas does not sell tickets or guarantee live schedules, fares, routes or alerts. Check with operators before travel. OpenStreetMap receives your IP when its map loads.
