For
Developers and people sharing precise locations
Worth noticing
The page marks its v2.1 specification as draft and says airport coordinates have not yet been verified against official sources.

Field notes

The code uses airport identifiers as anchors, then represents direction and distance with letter-and-digit groups; adding precision adds digits, while trimming them zooms out. The page reports 4,133 commercial-airport anchors and says the Python and JavaScript implementations were cross-tested on more than 78,000 cases. Its browser demo is described as running locally, but the captured page also reports that its map could not load.
