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…

Fieldnotes▲14Hi HN! I wanted a simple UI for notes and observations around my neighborhood (e.g. this garden has beautiful poppies, this coffee shop has excellent espresso, etc.) and built this. It’s open and free to use, I hope you enjoy it as much as I do! Feedback welcome.

UpToWhere▲28The idea came to me after spotting the sea peeking through mountains on a drive near Barcelona. It left me wondering what else was visible from different locations. Some of the features I later added include 3D maps, sun path calculation, adjustable elevation (calculate from a drone/plane POV), and mountain detection. To celebrate the launch, the first 100 HN users can get 1 month of free premium access with the code: UTWfirst100. I’d love your feedback, questions, and suggestions. What would you use this for? What features would you like to see?
