I saw this Met Office 'UK climate districts map' online so naturally I decided to try and figure out the population of each area whilst eating my lunch and these are the incredibly interesting results

there is also the Met Office "climate regions" map but that's a can of worms that I don't want to open, not least because of the unwavering England N / England S line

Okay, some European population density stuff now - starting with the top 100 1km grid squares by population across Europe, based on the most recent Eurostat data - more to follow these are the top 3 by density, but I've shared a web folder with all 1km grid squares with more than 30,000 people living in them, as well as the top square in each of the 38 countries in the dataset

Topical retweet because I've been watching The Rig but also the news - I remember first seeing these when I was about 10 when playing football in Invergordon and we couldn't believe the size of them

if you want to get a sense of the scale, look at the size of the people cutting up this old rig in Invergordon last summer

Another very interesting recent England and Wales Census 2021 release is the passport data, so here's a map of % with no passport at MSOA level, will add a couple more below these are all the different columns in the dataset (TS005Passports held) and the patterns are quite interesting, although I've only done a few maps as a way to explore the data

Today's census map shows the most common housing tenure in each local authority in England and Wales 🏡 I'm working on my spelling of mortgage, probably due to the shock of seeing how many households own without a mortgage!

More Census age data today - a little animation of % by single year of age in each local authority. Probably needs a few watches to sink in - lots in here - but the final 10 seconds I find quite sombre, and you'll NEVER guess when lots of people leave home and, just to go all dataviz retro, here are all the frames as small multiples

A little data nugget from this week's (very unusual but still useful and interesting) travel to work data, using LSOAs

-map on left is areas where 25% or more worked from home in 2011

-map on right is the 2021 version

let's wait 10 years and see what happened next and yes that is a helicopter in Richmondshire

🥳Free one hour mapping tutorial, tomorrow Thur 3 Nov at 13:00 UK time* (9am EST, 14:00 CET, 16:00 Istanbul, (00:00 Sydney, sorry)) - all welcome🥳

#30daymapchallenge this is a bit of an experiment that I have been planning to do for a while so let's see how it goes - so long as you know the basics of QGIS you should learn some useful new stuff for design, and possibly more

Reading the excellent @JonnElledge substack yesterday and obviously skipped straight to the 'measuring city size', featuring the addictive @thomasforth population around a point tool, and it got me thinking...

jonn.substack.com what do you get if you extend the distance to 100km around a point (e.g. as a very rough proxy for longer post-Covid commute zones) and do it systematically every 5km across the whole UK?

Big news from the UK today that I am truly excited about. Finally got my hands on the new book from the brilliant @theboysmithy - beautiful, super-interesting and a really enjoyable read. I actually saw a full manuscript before the print version came out so my pristine paper copy is now about to be thoroughly thumbed

What do the highlighted constituencies have in common?

Answer will appear below when someone gets it (or when I post it) but consider yourself a fully certified map twitter expert if you already know it. lots of answers that could potentially also be correct - and which demonstrate next-level nerdery - but whoever goes forth with the true answer will surely be crowned twitter map champion forever

Map of the day is a very comet-style UK general election 2019 map experiment, where

- colour of dot = winning party
- comet trail colour = second place
- comet train length = how far behind second place was

(dot is just a coloured centroid, see Alt text for QGIS geom gen code) also possibly interesting but also possibly meaningless is the line on this 'who came second in 2019' map

🚨Big new batch of local GIS open data resources 🚨 for Great Britain - based on OS and ONS open data - a shortish thread (data for all local authorities individually, as well as full Great Britain files, all in one place - see screenshot at link below)

automaticknowledge.org/gb/ there's buildings, greenspace, places, rail (stations + lines), roads, water - all for single local authorities, or for full Great Britain, if you need it - and simple file names so you can tell what's what - e.g. here's the buildings folder

A little bit of Highland map therapy this weekend, in 8 steps probably enjoy this more than watching the news, it has to be said

Obscure map mystery of the day for people who enjoy this kind of thing even though there are loads of points this is of course a bit pointless but I will keep the torment going and post answer eventually 🤓

this isn't about becoming a billionaire (🤫) but about providing a systematic, affordable fun way to learn, with interesting examples - using data from across the world (we currently have people from 121 countries)

I'm working on the next course (more advanced) too

Short map thread on geography of jobs across Great Britain, by sector, at local authority level. Coloured areas show where at least 1 in 10 jobs are in a particular industry (data: BRES 2020, ONS) - top areas are labelled I've been working with BRES data quite a lot in recent times, so thought I'd take a closer look at the patterns - Northern Ireland sadly not included in this dataset. I was surprised by some maps, but not others

Just back from Iceland, where about 85% of all houses are heated with geothermal energy, so a short thread on global energy data with a few quick maps (maybe I am avoiding my post-holiday inbox) - pic is of Svartsengi Geothermal Power Plant, taken last week the World Resources Institute (@WorldResources) publish the Global Power Plant Database, and this contains the location (lat/long) of approx 35,000 power plants worldwide, plus details on primary fuel and generating capacity, etc

A long blog post in which I:

- explain how to turn a sequence of images (maps, but could be anything) into a video, as in the example here

- give away all sorts of trade secrets

- share some image sets to play with

- provide lots of example commands

statsmapsnpix.com/2021/12/map-an… I cover installation of #ffmpeg on Mac (easy), Linux (easy) and Windows (easy, but can seem horrendously complex for new users) and ...

A little bit of map fun today with elevation data - a kind of topographic map, with lower elevations filling up first - spot the Danube, the Alps and all sorts of other things (elevation data from @CopernicusEU) a few stills from the topogiffic map above - I'm not an expert but that looks like the Great Hungarian Plain

Weird alien eyeball? Or world population by latitude? Just another map experiment but since it fits with today's #30DayMapChallenge theme I'll share it here

statsmapsnpix.com/2021/11/world-… I included a population vs land by latitude gif too, because it seems people don't like to live in the sea
