Globalhash
The decimals generated by the geohashing algorithm can also be used to generate a single point on the globe instead of one for each graticule and this award celebrates those lucky or mad enough to pursue that single point.
To generate this point take W30 decimals for a date (to make it global) and multiply the latitude by 180 and subtract 90, and the longitude by 360 subtracting 180. This will generate a single point on the globe which is today's only globalhash.
Proof is the same as any hash, but at the single day's coordinates. Good luck! The odds of the globalhash falling in your graticule are 1 in 64,800!

Example
For 10 September 2008, the W30 decimals generated were 0.2642955149758937 and 0.45661491254372155 for latitude and longitude respectively.
0.26429551497589370 * 180 = 47.5731926957 - 90 = -42.4268073043° Latitude 0.45661491254372155 * 360 = 164.3813685160 - 180 = -15.6186314840° Longitude
Or 42.4268073043° S, 15.6186314840° W which is in the south Atlantic Ocean, near Gough Island.
Locations
- KML ¦ Google Maps - all globalhashes, beginning 2008-05-26 until 2008-09-08.
- Online Globalhashing Tool - Look up any date since 1928-10-01.
- DAGAAG (Danatar's Approximate-Globalhash-At-A-Glance manual lookup map): If the online tool doesn't work and you want to avoid difficult calculations, just have a quick glance at the approximate location. Take the W30-adjusted coordinate offset (e.g. from the peeron map, but don't use American graticules) and compare it with the map using the black grid lines. If this gives a location at the other end of the world, you don't have to think about it any more, but if it is near you, you will have to use a calculator to get the exact location. See example here (for 2008-09-10 like in the other example above).

Honorable mentions
- David Souther made it within 8 miles of the 2009-03-04 globalhash before Mother Nature turned him back.
Upcoming Locations
* May 11, 2009 offers an incredible opportunity for the intrepid Globalhasher. Located, as near as I can tell, exactly on the Clark Fork of Red Creek in Yosemite National Park, this location sits approximately seven miles (as the crow flies) from Curry Village, and about a mile and a half from the nearest hiking trail. If you choose to accept this mission, you will collect (at least) three achievements: Globalhash, Water Geohash, and MNIMB Geohash. Good luck!
Somebody's calculations are a little out. The globalhash for Monday 11 May 2009 is at N 87°18.227', W 124°10.674'. -- Benjw 14:31, 8 May 2009 (UTC)
