Show HN: An interactive map of US lighthouses and navigational aids
This is an interactive map of US navigational aids and lighthouses,
which indicates their location, color, characteristic and any
remarks the Coast Guard has attached. I was sick at home with the
flu this weekend, and went on a bit of a Wikipedia deep dive about
active American lighthouses. Searching around a bit, it was very
hard to find a single source or interactive map of active beacons,
and a description of what the "characteristic" meant. The Coast
Guard maintains a list of active lights though, that they publish
annually (https://www.navcen.uscg.gov/light-list-annual-
publication). With some help from Claude Code, it wasn't hard to
extract the lat/long and put together a small webapp that shows a
map of these light stations and illustrates their characteristic
with an animated visualization.. Of course, this shouldn't be used
as a navigational aid, merely for informational purposes! Though
having lived in Seattle and San Francisco I thought it was quite
interesting.
