A map showing the lighthouses of Europe has gone viral<\/a> on social media. It\u2019s a Geodienst project<\/a> that actually dates back to 2017 or so. The map is generated using lighthouse data extracted from OpenStreetMap. \u201cMore specifically, it asks the Overpass API<\/a> for all elements with an seamark:light:sequence<\/code> attribute, decodes these, and displays them as coloured circles on the map using Leaflet<\/a>.
