Some details: It combines near real-time images from multiple geostationary satellites, updated every 10 minutes (with a delay of ~30 minutes). NASA GOES satellite for the Americas, Japan's Himawari-8 for Asia and Meteosat in Europe/Africa. Zoomable up to 500m per pixel. Beyond that it uses historical imagery from Microsoft and Esri.

It also tracks the latest storms and hurricanes https://zoom.earth/storms/

Can you use ESA Sentinel satellite imagery as an intermediate step? It's 10m ish resolution updated on a roughly weekly cadence.

I use it frequently (via https://apps.sentinel-hub.com/sentinel-playground/) to help plan backcountry trips around here, as it's great for seeing the local snow conditions.

I’d love to, but their API is currently cost prohibitive for a free-to-use website.

[jrichardshaw]

Oh, that's interesting. ESA says they distribute the Sentinel data free of charge as far as I can tell. So I guess the issue is that you'd need to download and host the data yourself, rather than just do an API call to someone else's archive?

Anyway, it's a cool website, nice work!

[zetalemur]

Yeah and hosting it by yourself is slightly non-trivial as the storage requirements are in the PB range.

You’re exactly right. Sentinel Hub process a huge amount of data in real time, so it’s no small feat.
