    Fun fact, there is a .gov effort to sell (or give away) a lot of old lighthouses in exchange for agreed maintenance. It's sort of a terrible deal, since you can't live in them or use them for commercial purposes, but you do still have to maintain it to a certain standard. But I'm sure someone is out there with the desire.

    I like the idea. But it was a bit jarring that panning with my finger took ages and then pinching to zoom insta-faceplanted me into the Labrador interior.

    If anyone wants to mount a rescue, I’m somewhere near a lighthouse.

      Even on desktop panning is remarkably slow.

    Fun fact: lighthouses in a general area will all have different periods so sailors can easily tell them apart and know which one they are looking at

      They also have different fog horn timings as well.

      sounds like pulsars.

    What an incredibly annoying zoom/spin thing is going on there

    Pinch to zoom on a macbook makes the entire map sweep across the globe. Makes it very hard to use even if it's a neat idea.

      Happens on desktop with Firefox as well.

      Looks like a bug with the view origin point being mis-matched with what the view's actually focused on - maybe high-DPI scale mis-match?

      Sounding like desktop/laptop with a mouse is the only way to interact with this site. It's a great first try though. I spent a few minutes poking around for sure.

    I checked the area near my house and there are about 10x more lighthouses shown than really exist. Some are buoys but most don’t correspond to anything.

      There is one next to me that is not shown, so more of a coastline viewer than a lighthouse one.

    My favourite bit about people who use OpenStreetMap data for lighthouses is that they end up including <https://www.google.com/maps/@52.2647013,-2.1151705,51a,15y,2...> lighthouse in the exceptionally landlocked Droitwich (shows up as Hanbury Wharf Lighthouse)

      They also often include "pairs" of lighthouses (high / low, front / rear) where newer ones have replaced older ones, but the older structure is still there (and often is now a museum), but isn't the active lighthouse.

      Although this one has done a reasonable job at culling most of those out, at least on the south coast of England.

    It's cool data and I wish the person who prompted Claude to build this would have at least made an attempt to make it optimized and readable. Like, what does "Fl • every 5 s" mean? It's frustrating because this could have been amazing!

    Looks cool but on iPhone can’t zoom with touchscreen, and can’t tap either to select a lighthouse.

    The US state with the most lighthouses isnt on the coast.

    I’m talking about the true lighthouse count. I understand there are some issues with this map.

      Do you mean sea coast? Quite a few larger lakes and rivers have them.

    My M4 macbook pro ramped up it's fans to 100% after being on this site for three minutes

    Didnt know there were lighthouses on the French Antarctic Kerguelen Islands
    • nephihaha 19 minutes ago
      They are not in a busy part of the ocean, but I suppose it is to warn people away. That archipelago is not fully charted, so it is probably a good idea to keep away from much of its coast. Probably dozens of uncharted reefs.

    It jumped around when I tried to use it on a mobile phone. I was surprised how few Greenland has.

    I'm fairly sure that there are more in outlying islands of New Zealand. The Chatham Islands seem well marked but there are none marked on Stewart Island or the Snares.

    Never knew about lighthouses on land
    • nephihaha 18 minutes ago
      They're on rivers, inland seas and large lakes. Russia has a lot because it is heavily reliant on waterways.
