Anyway, it's a really nice service, good job! :) Hmmm, I was thinking of a bookmarklet that would calculate the geohash, since I didn’t know about the “?q=” parameter.

The video game approach mentioned includes a punctuation mark, and both 1 and l. I've picked a set that would prevent the first two issues entirely, and do some work on the last one, since doing entirely wasn't possible (and hey, being in greenland is awesome.. it's surely a good thing to do there). Greetings Roberto, Coincidently, I already have such a bookmark. I had one before just to look at the coordinates, so it was straightforward. Try to bookmark <a href="javascript:p=gApplication.getMap().getCenter();window.location=%22http://geohash.org/?q=%22+p.y+%22 %22+p.x;" rel="nofollow">this link</a>. Hey Dorneles,

There were a few goals in the character set chosen:

  1. No punctuation
  2. Avoiding similar glyphs (e.g. l and 1)
  3. Removing vowels to avoid forming natural words

A nice addition would be a bookmarklet for Google Maps, which would give the geohash for the central point in the current map. I'll try to implement one, it should be a fun way to understand the algorithm in detail. Nice, it’s a really clean and elegant solution!

I noticed that you aren't using the standard Base32 data encoding defined by the RFC3548, but a slightly modified version from it. That said, I'm curious to know why did you choose the current mapping... :-) As a suggestion, what about use the video-game approach for mapping it: http://en.wikipedia.org/wiki/Base32#Video_games This certainly will help to avoid generating profane geohashes like, for example: http://geohash.org/fuck Which, despite being in Greenland, is a valid geohash now... :-) Hey Gustavo,
