Today's location: peeron google osm bing/os kml crox

This graticule covers the part of the United Kingdom from 51° to 52° latitude, and from 0° to 1° longitude. It contains the East End of London and extends through Basildon to Southend-on-Sea, also covering Maidstone, Chelmsford, Harlow and Colchester. It includes such diverse locations as the O2 Millennium Dome, the Isle of Sheppey, and London Stansted Airport.

To natives, this graticule presents a minor inconvenience in the form of the River Thames, which cuts neatly through the centre. As the Thames is crossable only by a) going into London, b) paying a toll at the Dartford Crossing, or c) swimming like crazy (not recommended).

When following the XKCD geohashing algorithm, append the fractional hash part to 51° latitude and 0° longitude.

Planned Expeditions

Past activity




All geohashers are cordially invited to the 10th anniversary 2018 geohashing day meetup in the Cambridge UK graticule.






  • 2011-01-08 51 0: Sourcerer visited the Hucking estate and nature reserve. Be careful how you enunciate that one. Hucking lies between Maidstone and Sittingbourne, Kent, UK.


  • 2010-09-24 51 0: Sourcerer visited a harvested wheat field north of the village of Anstey on a dark windy moon-lit night. This was hash 2 of a pentahash taking in Canterbury, London East, London West, Northampton and the Cambridge graticules.
  • 2010-01-19 51 0: Benjw once again headed to Stansted Airport from Cambridge, but found the hashpoint in the airport carpark this time.


  • 2009-08-03 51 0: Mito got within 10 meters of the point near Otford rail station, it was on private land.
  • 2009-04-19 51 0: Dave Dubya attempted to reach the location (on the A414 between Chelmsford and Chipping Ongar), but it was situated on private property and farmland and so not directly accessible.
  • 2009-01-15 51 0: Benjw visited from the Cambridge graticule, and successfully reached a grassy area just off a track near the B1256, south of Stansted Airport.


  • 2008-07-15 51 0: (tr00st) attempted to head over by bike for his first attempt at getting to some coordinates... Arrived at the field the coordinates were in at about 5:45pm - vegetation proved too thick for me to actually make it to the right point, got pretty close.
  • 2008-06-23 51 0: A group from Maidstone and its surrounds are heading out to this conveniently close hash by foot, by bike, but probably not by plane. The hash may be sneakily relocated to the woods nearby if the field is found to be full of rapeseed for hay fever reasons.
  • 2008-06-14 51 0: The co-ordinates are in the middle of a field, with the closest civilisation either the small town/village of Hunsdon or the town of Ware. Reached by walking across country from Roydon train station. Found a swamp.
  • 2008-06-07 51 0: In darkest Thamesmead, just off the 244 bus route. Could only take sly photos due to dodgy looking locals.
