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)
