Thanks for posting!
I've recently added more datasets, "Places", "Birds", "Photos", and "You".
Also, a hint - the rectangular selection tool lets you generate custom reports for a location.

This is super cool.
Where is the bird dataset coming from? I assumed ebird at first, but these datapoints don't map on to ebird hotspots...
Also, where did you get the collection of creative commons licensed bird species photos?
The main birds dataset is from eBird, and the photos are from Wikipedia.
what's going on around colorado springs with these shapes?

The ”race tracks” are left- and right-hand traffic patterns for arriving aircraft and touch-and-go training, typically used by smaller aircraft. The polylines going from airport to the surroundings are IFR (instrument flight rules) STARs (standard terminal arrival routes) for inbound/outbound planes; each vertex in the line corresponds to a so-called navigation star which usually has a 5-letter name.
COS's airfield is also used by PSFB so you'll see different patterns than a normal airport. You find similar patterns, though, near other military bases like here, near Pensacola and Eglin:

Possibly training flights; they will often do racetrack shapes like that for long periods to maintain proficiency with the aircraft type.
What is "You"? I tried reading the query to understand but couldn't figure it out
I'd like it if you try to guess :)
But it is easy to figure it out from the source code. The source code is here: https://github.com/ClickHouse/adsb.exposed/blob/main/index.h...
Apparently my 'easy' isn't the same as yours. There's nothing I could find in the code that describes what it is. You'd have to make a pretty big logic leap to figure it out. All you can see in the code (in config.js, not in index.html) is the dataset url (random string) and the description "this website", which tells you very little.
For anyone who just wants to skip to the answer, I found it in the pull requests / issues: https://github.com/ClickHouse/adsb.exposed/issues/47
Interestingly it seems to line up quite well with population density maps.
It appears to be where "you" (website visitors) have loaded page tiles. I was able to draw a little picture on the map by zooming in and panning around!
The PR introducing it is easier to read than the whole repo: https://github.com/ClickHouse/adsb.exposed/pull/48/files
Awesome work, but please consider providing some contrast options. You can't see the country or continent boundaries unless they are full of tracks (or at least I can't.)
Haha, great! Honestly where did you get some of these datasets? Birds????? :)
