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
plus there are all sorts of other odds and ends in that /images folder!
PS for any font nerds out there, it's Righteous
☝️ these are mainly playthings, but the methods behind them have their uses, including figuring out how far away everywhere is from Murmansk, and many more real-world applications

'random Canadian-Scottish geography questions you can answer quickly while having your breakfast at the weekend'
- I may also have calculated the Scottish-Latitude population of Canada while I was at it, surprisingly low
plus, not everyone knows that the northern bits of Shetland are further north than the southern tip of Greenland - and even when you hear this you are duty-bound to check it yourself on Google maps because it sounds made up
the answer to my vital question, thanks to some 10km gridded data, is that a little over 570,000 people would appear to live at Scottish latitudes in Canada, and I think we can all sleep easy now
A short city population/datanerdfest coming up in this thread, beginning with a little panoramic tour of the Tokyo metro area - city as far as the eye can see
(I made this using Google Earth Studio btw, a very useful tool)
background: I have been using/playing with/analysing global city population data quite a bit over the years, most recently in an academic paper on the topic with @CJHoole and @stehincks
we looked at population density for the whole world, using 1km resolution data from the EU's GHSL project - e.g. here's a little snapshot of how it looks across part of West Africa, from our paper
Here's the final version of the global population density graphic I made, because another one that is circulating was less well defined, and someone cropped NZ off it
this is the little 'About this print' sheet that goes along with it
and, should you have a burning question like 'how can I make one of these?' or 'where do I get the data?' then see my blog for all the answers
Possibly of use for UK boffins, data journalists and the like: our (beta) version of a single UK local authority file with insets included (+ all area codes) - join data once, turn insets on/off as required
the bounding boxes are included as well, in a separate file
If you just wanted main map + an inset for London, you could filter layer like this:
"inset_area" IN ('Greater London','None')
you get an inset, you get an inset, everyone gets an inset - except they don't - we may do a version 2 at some point with (e.g. South Wales, Teesside) but for now this is inset in stone
