 FixPhrase.com uses an open source, patent-free algorithm to convert latitude and longitude into a set of four words from a word list.  Those four words (a FixPhrase) can be put back into the algorithm to get the original latitude and longitude.
 
-FixPhrases can be shorter than four words too if less accuracy is required.  The first two words will locate a city, the first three words will locate a neighborhood, and all four words will locate the corner of a house, the pitcher's mound in a baseball field, or six adjoining parking spots.

+The words in a FixPhrase are ordered alphabetically, and each word is taken from a different portion of the word list. This means the words in a FixPhrase can be entered in any order but will always translate to the same location.
