About once every 25 years, it becomes possible to be in the uncertainty circle of both hashpoints simultaneously if the longitude is less than +/- 0.000100°. For now, we track the closest distance between two hashpoints.

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.

Revision as of 21:59, 28 March 2016

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

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.

News

  • 2016-03-14 (Pi day): The Tongs bought a Holux M241 GPS logger to record more and better tracklogs.

Expeditions

The Tongs are at Level 3.

  • FL(n) is the Fibonacci Level of n, the greatest i such that Fi ≤ n, if Fi is the ith Fibonacci number. This means the Tongs are at Fibonacci Level 7.
