Another option is EZCOD: all the features of Open Location Codes, plus error detection and correction using Reed-Solomon FEC (forward error correction), in C++, Javascript or Python: https://github.com/pjkundert/ezpwd-reed-solomon https://github.com/pjkundert/ezpwd-reed-solomon A reference implementation is online at http://ezcod.com http://ezcod.com More details at http://hardconsulting.com/products/13-reed-solomon http://hardconsulting.com/products/13-reed-solomon TL;DR Friends don't let friends use geolocation codes without error detection! You'll end up in the wrong hemisphere... A code like "R3U 1JU QUY.0" gets you within +/- 3 meters of the coordinates 53.655832,-113.625433 -- with the ability to recover from 1 lost symbol, or a certainty of P(.969) that the presented code is correct. Optionally, 15 symbols gets you within +/- 20 millimeters of any location on the planet with P(.99997) certainty of correctness, or recovery from up to 3 missing symbols, or 1 erroneous symbol while retaining P(.969) certainty of correctness!
