I thought it might be fun to try to map the limits of my geocaching/geohashing. That is, to draw the smallest possible convex polygon that surrounds all of the geocaches I've found and geohashpoints I've successfully visited.

Mathematically, such a shape is a convex hull - the smallest map, geography, maps, geohashing, geocaching, programming, php

Background
I was contacted this week by a geocacher called Dominik who, like me, loves geocaching.... but hates it when the coordinates for a cache are hidden behind a virtual jigsaw puzzle.

A popular online jigsaw tool used by lazy geocache owners is Jigidi: I've come up with several

Cache removed and temporarily disabled. The council have just started installing new signage to advise of a new 20mph speed limit around here. 🎉

When they recently did the same in a nearby village, they removed a cache of this type as a (presumably accidental) side effect. I don't know if this c cache log, geocaching, driving

Background and hypothesis
When geocachers find a geocache, they typically "log" their find both in the cache's paper logbook and on one of the online listing sites on which the cache's coordinates can be found.

I've been finding and hiding geocaches for... a long while, so I've seen lots

This week, Ruth and I didn't go the Isle of Man.

It's (approximately) our 0x10th anniversary, and, struggling to find a mutually-convenient window in our complex work schedules, we'd opted to spend a few days exploring the Isle of Man.

A year and a half ago I came up with a technique for intercepting the "shuffle" operation on jigsaw website Jigidi, allowing players to force the pieces to appear in a consecutive "stack" for ludicrously easy solving. I did this partially because I was

For GC9EXXX Church Micro 14129...Sutton, a geocache I recently set up, I wanted to use a "pole topper" style cache. I've always felt slightly let down by finding yet another magnetic nano stuck inside a pipe, so I wanted to do something better.

We might never have been very good at keeping track of the exact date our relationship began in Edinburgh twelve years ago, but that doesn't stop Ruth and I from celebrating it, often with a trip away very-approximately in the summer. This year, we marked the occasion with a return to Scotland,
