Beacon map

This map shows all the blinking beacons from OpenStreetMap.

More specifically, it asks the Overpass API for all elements with an seamark:light:sequence attribute, decodes these, and displays them as coloured circles on the map. It also tries to take the seamark:light:range and seamark:light:colour into account.

Overpass API

The current version uses an extracted dataset, but the code allows for directly querying the Overpass API. However, since a query like the one used here can take multiple minutes to complete it is not very useful do always do live queries.

This map is made by the Geodienst because it was a fun idea we wanted to try out. Feel free to fork this map and make your own visualisation of OSM data, or contribute improvements back to us.
