For those geocachers who are also interested in geohashing, today's
geohash is easily accessible, in the Wilson Sports Complex area, right
next to the tennis courts. Kira and I will be attempting it this
evening. If others are attempting, it might be nice to try and do a
meet-up (the first for our graticule!) and then head out to find the
fantastic Imperial Night Game cache that's so close it might qualify
for a "Hash Collision" achievement!
A really short explanation of geohashing: Spontaneous Adventure
Generation!
A short explanation of geohasing:
Every morning a set of coordinates in your general area is
pseudorandomly generated and people try to get there.
A medium-length explanation of geohashing:
Every day a random set of coordinates within your 1°×1° latitude/
longitude zone (known as a graticule) (for us, this is (39°, -86°) to
(40°,-87°) ) is generated, using the most recent DOW opening score and
the date as a seed. The algorithm was invented by Randall Munroe in an
XKCD comic (
http://www.xkcd.com/426/) This way, you can't know where
the hash will be until the day it happens (or Friday, for weekend
geohashes). People try to get to that location. Often, they try to
meet other people, although our graticule is not very active, so while
there have been hashes with multiple attendees, they never happened at
the same time. When they get there, they take a picture of themselves
with their GPS device as "proof" of attendance, and when they get
home, they upload a description of their expedition to the wiki
(
http://wiki.xkcd.com/geohashing/). There are many achievements one
can get on the wiki, including ones for geohashes reached while
underwater, having a picnic at a geohash, being lucky enough to have a
geohash show up in your office, traveling the maximum speed limit
through the geohash, riding your bicycle all the way from your home to
the geohash, getting to geohashes in two different graticules in the
same day, getting to geohashes in two different graticules on the same
day at the exact same time (think: time zones), or even finding a
geoCACHE within line of sight of the hash (this might actually be
possible today, depending on the density of trees).
