I thought it was super cool. Love the other suggestions on other comments too. We should encourage such posts if not for anything but for allowing a tiny space for such discussions. Really hoping hackernews doesn't change its rules and member enforced etiquettes.

Well the only way to get “live” imagery at any level of perceptible detail is to be a three letter agency. Even the highest levels of private sector aren’t tasking satellites with that level of latency.

Sure, that's fair. But what / who then are they trying to sell the idea of with the phrase "live"? Is any average person really interested in a "live" view of the whole Earth, such that it would be meaningfully different or changed compared to the static blue marble photo we're all familiar with? I think we all know what we're interested in when we think of "live"... things at the <<1km level.

I'm super happy to see this website personally, seeing the weather patterns and being able to timestep through them historically is really awesome. I'm a sailor, so that's my angle.

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.

Thumbs down. Picture for where I live (Warsaw, Poland) seems from more than a year ago.

High resolution will be older imagery. You won’t be able to see your house in near real time unless you pay to task a satellite from a commercial provider like Planet Labs.

Is it theoretically, and practically possible for a private company to task a satellite with this level of latency/detail? Are there laws/regulations in this regard? Or is it more a technical/financial barrier?

Planet Labs do this (planet.com) but $$$

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!
