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. + +## Credits +This map is made by the [Geodienst](http://www.geodienst.xyz) 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.
