Today's location: not yet announced

The New York City graticule is at latitude 40, longitude -73. It includes most of New York City (minus Staten Island, the west tip of Brooklyn, the West Village & Chelsea and downtown Manhattan) and a whole hell of a lot of Long Island. That means about 10 million potential geohashers in this graticule. Sigh, if only our graticule were not mostly sea water... On the bright side, non-preppies can now visit the Greenwich, CT islands in this graticule via Metro North and ferry.

Today's Location: [New York, NY]

There is a facebook group for New York, NY geohashers.

Local Geohashers[edit]

  • Sputnik has been in Manhattan since August 2014 but did not manage to make any expeditions until July 2016. Is limited to areas reachable by the MTA, so cannot hash as often as I'd like.
  • Jevanyn is in the city once or twice a year, and may try to join a Saturday meetup.
  • Sempaispellcheck does not have a car and is very busy, but will try to geohash whenever possible.
  • Elipongo can bicycle, walk, take transit, or even his ambulance at work to geohashes; except for on Saturdays because of Shabbos.

Inactive Geohashers[edit]


Brandon earned the Virgin Graticule Achievement
by being the first to reach any hashpoint in the (40, -73) graticule, here, on 2009-02-26.


This seems to be one instance where the incredibly cool XKCD geohashing scheme fails. Many New Yorkers located in the city do not have cars due to the availability of public transportation and the lack of space to park said car. Because of this, people are disinclined to take the train out to Long Island.

  • This could be solved by congregating at or near the closest train (LIRR, MTA, Metro North) station when hashes occur in generally unreachable locations.
  • Another possible solution would be to use a Half-graticule algorithm to increase the chances of land-based geohashes.
  • A solution for geohashpoints in the ocean could be to determine the nearest coast-point from a geohashed point. Ryelle wrote a script called CoastSeeker back in the day, but it is no longer working.
