The Ordnance Survey are marking the 80th anniversary of the Retriangulation of Great Britain, which began on this day in 1936. More from BBC News. Events include the Trig Pillar Trail Challenge, which invites people to post pictures to social media of one of 25 selected trig (triangulation) pillars (the #TrigPillar80 hashtag is very busy this morning). There are Flickr galleries of various trig pillars from Flickr user Andrew (who took the one above in 2013) and (of course) the Ordnance Survey.
Coming next month from Policy Press, the third edition of People and Places: A 21st-Century Atlas of the U.K. by Danny Dorling and Bethan Thomas. The Independent has a long profile of the book, which makes extensive use of cartograms to illustrate data about the British population, and one of its co-authors, Oxford geography professor Danny Dorling. Pre-order at Amazon (direct Amazon U.K. link—it’s more likely to be in stock there). [via]
Every Person in Scotland Mapped, a dot density map by Heikki Vesanto with a bit of a methodological twist. Rather than randomize the location of population dots within a given postcode, the map “creates a random point within a building shell inside of a postcode area, which is repeated for every person in a postcode. This is in contrast to a simpler process, which does not take into account buildings at all, working simply with postcode areas.” Zoom in and see. [via]
YouGov’s eurosceptic map of Britain measures the level of euroscepticism in the regions of England, Wales and Scotland in the run-up to the U.K.’s upcoming EU referendum. “New YouGov research using the profiles data of over 80,000 British people on the YouGov panel reveals the most and least Eurosceptic areas of Britain, down to the finest detail our data will allow. There are 206 local education authorities in England, Scotland and Wales, 188 of which we have large enough samples to report a position on the EU.” [via]
The Ordnance Survey is currently running a map return scheme, in which customers send in their old maps in return for a voucher up to £15. It runs until March 20, but they’ve already received 9,000 maps so far. (A similar scheme in 2014 yielded 10,000 maps in total.) Some of the maps returned date back to the early 1900s. (I hope the OS makes sure they’ve got a complete set of everything; it wouldn’t do to give away the the last copy of an obscure older edition for an art project. If nothing else there’s an opportunity for a crowdsourced archive here.)
The National Library of Scotland has an online map viewer that overlays georeferenced old maps atop a modern web map interface (Bing, I believe). Among my crowd, it’s the various 19th-century Ordnance Survey maps of London that generate the most excitement, though there are plenty of other locales (mostly but not exclusively in the U.K.) and time periods.
It turns out that Samuel Fisher has also created a fantasy map of Great Britain, in addition to his Australian fantasy map and one version of the U.S. fantasy map. Again: an important data point for understanding what people think a fantasy map looks like. (His lettering is a dead ringer for Christopher Tolkien’s on the Middle-earth map.)
