Inspired by @pnorman’s animation, here’s a year of daily OpenStreetMap tile traffic. One frame per UTC day, from the start of September 2022 through end of August 2023. It’s from the public log aggregates, so some low-traffic tiles are left out for (I assume) efficiency and privacy.
The answers to your questions are:
1. Yacht and rally car races.
2. Yes, well noticed! We call it “Null Island”.
3. No, but it would be nice if it were practical.
4. People scraping tiles.
5. Yes, because the distribution of traffic follows Zipf’s law.
6. If I have time.
Woops, the tag didn’t work in the original post. Credit to @pnorman for the idea.
Same general idea and source data, but this time it’s just z-score (https://en.wikipedia.org/wiki/Standard_score), with red positive and green negative. Hard to say that this makes it easier to spot the interesting anomalies, but it seemed like the common sense thing to try. You can see the the OceanGate incident, the earthquake in Turkey and Syria, probably some festivals, etc.
Okay, fine, @jonty cajoled me into it. Lighter is more traffic; warmer is more positive anomaly for the day.
Now, certain nerds and haters might squint at this and say “It looks like you did this in oklab color space and then tried to half-ass some gamut mapping when you remembered that a lot of the highest z scores are in places with very low traffic counts!” and I would rebut that in scrupulous detail with one simple argument: Good night.
@vruba I like it! I love happy accidents like this and the palette is remarkable.
@vruba Juuuuuuuuust right.
@vruba Spectacular work
@vruba I mean I was going to say, (I wasn't but it's fun to think I could've if I knew how, so I'll just say, wow! cool!).
Ideally you’d have this over a basemap and with both dimensions (number of views and view anomaly) visible, but I will generously allow someone else to worry about that.
