All geohashers are cordially invited to the 10th anniversary 2018 geohashing day meetup in the Cambridge UK graticule.
- 21 May 2018 (Mon): An excellent celebration of Geohashing Day will take place at 4pm local time at a place yet to be determined.
- 26 May 2018 (Sat): is Mouse Over Day and might be more convenient so the invitation applies to this day too.
A field ploughed with straw...
The Tongs is a name for a group of friends who go geohashing in the Cambridge (UK) graticule, but who might stray into the Northampton graticule sometimes. We usually aim to visit hashpoints nearish us at 4pm local time, if it looks like there's something interesting in the area or if people want to meet up (we monitor our talk page, so leave us a message if you do).
Tongs/B's favourite joke: Q: What is the point of all this? Well, we just don't know until the day before.
Please feel free to say hello using email.

- FL(n) is the Fibonacci Level of n, the greatest i such that Fi β€ n, if Fi is the ith Fibonacci number. This means the Tongs are at Fibonacci Level 7.
Counting things
- Distinct graticules: 3.
- Total hashpoints bagged: 13.
- Hashpoints until we level up to Level 4: 3.
- Saturday meetups we've made: 2.
- People we've ever met doing geohashing: Benjw.
- Success rate so far: 100%
Achievement planner
- If the hashpoint is fairly nearby we could do the hobbit achievement. We should have tough enough feet.
Reverse regional achievement in (52, 0)
Assuming this is at the county level, we need to have visited six counties, of which Lincolnshire is the trickiest.
| County | First expedition |
|---|---|
| Cambridgeshire | 2014-08-17 |
| Essex | - |
| Hertfordshire | 2014-08-23 |
| Lincolnshire | - |
| Norfolk | 2015-08-30 |

Simultaneous doublehash in (52, 0) and (52, -0)
About once every 25 years, it becomes possible to be in the uncertainty circle of both hashpoints simultaneously if the longitude is less than +/- 0.000100Β°. For now, we track the closest distance between two hashpoints.
| Date | First | Second | Distance |
|---|---|---|---|
| 2014-08-23 | 52, 0 | 52, -0 | 8022m |
| 2016-03-12 | 52, -0 | 52, 0 | 3492m |

Another map
It would be very silly to do a best fit line on this map, so I plan to do that at some point.
This map shows the points we've visited. The opacity of each circle is proportional to the number of Tongs who visited the hashpoint that day. Grid squares are 0.1 degrees. You can see the counties we've visited - Cambridgeshire is in grey, and Norfolk to the northeast and Hertfordshire to the south.
