FixPhrase

FixPhrase is a simple algorithm and word list that enable converting a pair of GPS coordinates to a four-word phrase and back again.

There are currently JavaScript and PHP libraries available. Both are a single file containing the word list and the encode/decode algorithms, and both function identically.

Features

• The words can be input in any order without affecting the output coordinates
• Accurate to 12 meters or better
• The first two words of a phrase (when the words are ordered alphabetically) are sufficient to locate a city (accuracy better than 12km)
