All the lighthouses that illuminate the coasts of the North Atlantic, gathered in an impressive interactive map
The figure of the solitary lighthouse keeper in charge of the thankless task of keeping his tower operational and in good condition at the service of the boats has long been a rare sight: they are in danger of extinction in front of the automated towers, both in terms of lighting and other auxiliary tasks within of the DGPS differential system. There are (almost) no lighthouse keepers, but the lighthouses look like never before. Only Europe’s 90,000 kilometers of coastline They are a veritable garden of lighthousesbut one thing are lighthouses (that iconic tall tower with a light on top) and another is lights for maritime signaling, where large lights, small lights, beacons or buoys enter. The reference technical standard is IALA Recommendation E-110, as collects and translates into Spanish Puertos del Estado. If we talk about maritime signage, things change there and the figures increase: there are 23,217 lights in the northern seas alone, according to OpenStreetMaps. It must be considered that this is open data, provided by the community, with areas very well mapped and others not so well. The lighthouses of the North Seas, as we have never seen them If we stick to the northern seas, the lighthouses drop to around 2,500 units. Although his thing is teaching and business, Wharton University professor Ethan Mollick has condensed all this information into an interactive map using vibe coding: Lighthouse Atlas. Lighthouse Atlas This map of the northern seas is more than a mere cartography of that maritime signage: it is interactive, making it a tool as visual as it is impressive for the possibility of playing with zoom, filtering or the information it shows. If you also hover over the lights, you can see more data such as their name, color range or frequency. In addition to being able to filter to see only the headlights (‘Major lights only’), as Mollick explainseach light has the correct color, each flashes with the appropriate frequency, and its brightness has been scaled according to OSM data. You can also see how far away they are visible. How far are the light signals seen in the Atlantic, between the Spanish and French states Thus, the size of the points serves to get an idea of how close or far the vessels can be to view the signals. For example, on these lines you can see how much the signals of the muga between the Spanish and French states illuminate. Especially striking because of how congested the Norwegian coast is, as can be seen numerically. in the database from Norsk Fyrhistorisk Forening, the company that compiles a detailed map of locations along the entire Scandinavian coast. However, of the historical 212, it has about 150 operational. It is not the only one: Scotland and the Isle of Man, the coasts of Denmark and the Adriatic Sea, on the coasts of Greece and Türkiye are also well nourished.
