A little Cairngorms flyover, just for fun, with music #aerialod #ffmpeg (I also put a locator map in the top right)
method: Aerialod to create the tiles, ffmpeg to stitch them together and add the little map overlay (made in QGIS), title in Kdenlive, data from @OrdnanceSurvey, and landscape by glaciation
@OrdnanceSurvey command to patch together the c. 1,400 frames exported from Aerialod: ffmpeg -r 40 -i #####_%03d.png -c:v libx264 -s 1920x1080 -r 40 -pix_fmt yuv420p output_file_name.mp4

Then a couple more commands to add the music and the overlay inset map - gradually getting to grips with it

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
Image
Image
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

when you plonk the Met Office climate districts on top of a map then you get something like this Image

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

drive.google.com/drive/folders/…
they're all really interesting to me, but I particularly liked Gijón, Bucharest and Valletta

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
the Cromarty Harbour folk have done some nice street view imagery of the firth, e.g.

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

the % with Irish passport map looks like this - probably about what I'd have expected

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!
most common by area is of course a very first-past-the-posty representation of things but I'm interested in the pattern precisely because of this - will fix typo later, perhaps I should do by constituency too

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
nerd note: lots of ways to make small multiples from image sets but I tend to use ImageMagick, and the image above was created using this command:

montage *.png -tile 10x10 -geometry +5+5 age-by-year.png

Once you have a set of files it only takes a few seconds to run
