Sorry, you currently need to click to load another area. You can also navigate with the search bar or randomize by clicking the city icon.

I do want to load things automatically but need to figure out how to avoid hogging to much resources for contouring on the users device.

This is the first time sharing this, so a bit of an early release 😅

Works for me, but you have to tap on the city you want to see for the data to be displayed

Do you mind sharing the OS? This was developed on Firefox (Debian & iOS).

I don’t know if your WebGL is working correctly but I could try to add a check (and thus a more graceful failure mode).

Thank you for the report!

If you’re willing to share OS/browser that could help :)

I’m on the fence with adding Sentry as I was hoping to keep the project very privacy minded.

Yes, only European cities covered by Eurostat. I tried to cover this in the about section but it basically boils down to processing time, my own available time and to a lesser extent storage.

It took me more than a week to process 2013-2023 for the included areas, which is roughly 10TB of raw imagery (with less than 60% cloud cover).

The Eurostat urban extents, for the most part, delineate urban areas with a detailed vector dataset. This is something that I also couldn’t find on a global scale.

I’m not decided yet on expanding the extents, which also depends on if people actually find this useful. However, it is open source (AGPL) so it can easily be forked and adapted.
