From Geo Hashing

Welcome to the Geohashing Community Wiki. Geohashing is a method for finding an effectively random location nearby and visiting it, i.e. a Spontaneous Adventure Generator. Geohashing was brought to you by the xkcd webcomic.

“	Basically, we take a random point based on the Stock exchange and the current date, and go and have wacky adventures. Think of me as a new kind of adventure capitalist.		”

What is this?

The Algorithm as shown in xkcd comic #426, published on 21 May 2008.

Every day, the algorithm generates a new set of coordinates for each 1°×1° latitude/longitude zone (known as a graticule) in the world. The coordinates can be anywhere -- in the forest, in a city, on a mountain, or even in the middle of a lake! Everyone in a given region gets the same set of coordinates relative to their graticule.

As such, these coordinates can be used as destinations for adventures, à la Geocaching, or for local meetups. After the fun, please document your expedition! The rest of us would love to read your story, see your photos, and cheer your success (or commiserate with your failure). You can use this wiki to document the daily coordinates (geohashes) you’ve been to or tried to reach.

Official xkcd meetups

Rhonda, Robyn and Wade at the 25 April 2009 coordinates for Vancouver, BC, Canada

Official xkcd meetups happen every Saturday afternoon at 4:00 p.m.(*) at that day’s normal geohash coordinates. It is considered a Saturday meetup if you are there at 4:00 p.m. or if you meet people, but you are most likely to encounter other readers of xkcd if you go at the designated time. Bring games!

You're encouraged to geohash on any day of the week that the coordinates are accessible to you, but if you attempt one meetup all week, make a little extra effort to have it be on Saturday. All meetups start at 4:00 p.m. or as designated on the graticule page.

There's even an achievement for making it to 100 Saturday meeteups.

*In some areas, 4:00pm is too close to sunset during the winter, so earlier meetups are often more appropriate. See individual graticule pages for local conventions.

Recent and Upcoming Coordinates

The coordinates for the Saturday meetups on 4 July 2009 are now available. The coordinates for the next Saturday meetups, scheduled for 11 July 2009, will be based on the Dow’s opening price published at 09:30 EDT (13:30 UTC) on Friday 10 July. See timeanddate.com to convert this time to your local time zone.

Disclaimer: When any coordinates generated by the Geohashing algorithm fall within a dangerous area, are inaccessible, or would require illegal trespass, DO NOT attempt to reach them. Please research each potential location before attempting to access it. You are expected to use proper judgment in all cases and are solely responsible for your own actions. See more guidelines.

Gallery of Recent Expeditions

The gallery for each day is added to this page automatically, but pictures are selected to the gallery by us. Any geohasher is welcome to add a picture from that day. Just add your image name in the list at the “add yours” link. If the gallery hasn't been started yet, copy the format from the previous day, or read the how-to. Please also write an account of your expedition, even if only a short one, so that people can click the link on your picture and find out more.
