Bienvenidos al Wiki de la Comunidad de Geohashing en español. Este wiki ofrecido por el webcomic xkcd.


¿Qué es esto?

El algoritmo como está en xkcd cómico #426, publicada en 21 Mayo 2008.

El <<Geohashing>> es un método para encontrar un lugar aleatorio cercano y visitarlo: un generador de aventuras espontáneas. Cada día, el algoritmo genera coordenadas para cada cuadrado de lado 1 grado que hay en el mundo. Las coordenadas pueden apuntar a cualquier sitio: Al bosque, a la ciudad, a la montaña o incluso al medio de un lago. Desde una misma región del mundo, todos obtendrán siempre las mismas coordenadas.

Por ello, estas coordenadas pueden ser usadas como destinos de aventura, a estilo del <<Geocaching>>, o para encuentros locales. Después de la diversión, ¿por qué no documentar tu expedición?. El resto de nosotros disfrutaríamos enormemente leyendo tu historia, viendo tus fotos y celebrando tu éxito (o ayudándote a sobrellevar tu error). Puedes usar esta misma wiki para aportar las coordenadas diarias que has intentado o vas a intentar.

Descargo de responsabilidad:' Cuando cualquier coordenadas generadas por el algoritmo <<Geohashing>> entran en una área peligrosa, son inaccesibles, o sería necesario allanamiento ilegal, no intente acceder a ellos. Por favor, cada posible locación de la investigación antes de intentar acceder a él. Se espera que el uso adecuado sentencia en todos los casos y son los únicos responsables de sus actos. Lea las directrices.

Encuentros oficiales

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 meetups.

*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.

Coordenadas Recientes y Próximas

The coordinates for the Saturday meetups on 19 September 2015 are now available. The coordinates for the next Saturday meetups, scheduled for 26 September 2015, will be based on the Dow's opening price published at 09:30 EDT (13:30 UTC) on Friday 25 September. See timeanddate.com to convert this time to your local time zone.

Recent Expeditions


Add the things you think need to be done, but can't do yourself. Remove the bullet points when you've fixed something.

  • The link on the iphone app page [1] labelled Geohash support is broken
  • Jim removed an apparently invalid expedition and photo from 2009-01-10 Someone should see if the real 2009-01-10 29 -95 is hiding someplace that isn't obvious.
  • Expedition Archive pages (like [2]) show same coordinates for every day (looks like an error)
    Started a discussion here: User_talk:Tjtrumpet2323#usage_of_var:latdate_on_Template:Coordinates.2FRegular.2FlatOnly.3F - a correct use of vardefine:* might fix this if it's not going to break anything else.
  • Does anyone have access to LocalSettings.php to set $wgUseTeX = true; so that formulas can be used? Or is there some other way to enable them that I'm not seeing? Thanks! -ralph
  • Kids' Geohash? If they have a GPS enabled phone they can take part but the grid is too big so divide it into 32, 64 or even 128 for younger kids. Parental supervision recommended!
  • anything in Category:Needs attention might also be considered a kind of TO DO, especially Award template needed and Ribbon image needed
  • 2011-06-26_49_8 has category Category:Meetup in 49 8 on it, but doesn't appear on that category page. Is something wrong with the graticule Template? (We had a problem with spaces between the colon and the category name at one time.) Jiml 10:22, 27 June 2011 (EDT)
Not sure what you mean, 2011-06-26 49 8 is on the category page and that's the equivalent name with spaces (they are interchangable), am I missing something? - Mampfred 16:48, 27 June 2011 (EDT)
It seems to be showing up on the category page now. Not sure why the problem disappeared. Jiml 22:04, 6 July 2011 (EDT)
  • I need a GEOHASH ALARM. An email to be sent to me every time the selected point is close enough to me (like less than 5 miles, for example).
Your wish is my command. Register an email address at http://xkcd.nathanwoodruff.com/Notify.aspx It will send you an email with a password. Log in and enter a Graticle Latitude and a graticule Longitude in the Grat Lat and Grat Lon boxes 33 -84 for Atlanta Georgia. If you want to enter the Global Hash, check the Global box, Then enter a Location Latitude and Longitude in the Location Lat and Location Lon. 33.75 -84.39 for the dead center of Atlanta Georgia. You will need to enter a maximum distance. If you enter 5 miles it will send an email if the days coordinates for the chosen graticule is less than 5 miles away. Click on the "Add" button. It will send you an email from now on every day after the Dow open is released. --NWoodruff (talk) 18:25, 13 November 2014 (EST)
