Ask HN: Shortest string representation of GPS coordinates?
What is the shortest possible way to encode valid GPS coordinates (with reasonable precision) as a readable string?
Should I be looking at `baseXY` encoding schemes or totally different spacial representation system?
If you're curious it is for a tattoo I want to get, and I think the shorter, the better it would be!
Plus Codes[0] seem to be an option, but I'm not really into the idea of putting something pushed by Google on my body instead of a standard.

- sizzzzlerz 6y agoThe Maidenhead system, used extensively in ham radio, can encode latitude and longitude in 6 ascii characters to a precision of 10.4 km, or 6.3 miles. Adding two additional characters can reduce that even further. https://en.wikipedia.org/wiki/Maidenhead_Locator_System https://en.wikipedia.org/wiki/Maidenhead_Locator_System
- Raed667 6y agoThat looks awesome! With 8 ascii characters I get the exact precision I need. My only regret is that the GPS Lat/Lng with N/S E/W is a immediately recognizable
