> Parts of the landmass can also be missing due to complete cloud cover that day. See the Amazon, Central Africa, or Northern Australia for example. Aka great places to start a terrorist or drug organization! The invasion of Iraq got delayed by a few days due to cloud coverage. It would definitely impede surveillance to have clouds often blocking satellites.

This is where SAR imagery comes into play [1]. There are a few SAR constellations online and being worked on that are shifting the discussion about what we can track [2][3].

You can access their monthly imagery for free by creating an account at planet.com. I use it to track the progress of infrastructure and other land development projects near me. You can also create time lapse animations of a particular area, which is a super fun way to watch a road or a highway being built.

What is he resolution like? Is it as good as Google's aerial imagery that they show with their maps? (or Bing's)

Absolutely great, I am sure we will need these kind of visualizations to survive. But the planet needs a JavaScript programming competition with the challenge of minimizing CPU load of such fantastic presentations. It would be so good to have one golden path to browser animations with the lowest energy consumption, one default framework that will be easy to use without deep knowledge of browser quirks and JavaScript…

Well, I would say, what we need and have is a rich ecosystem of JavaScript applications, which can and does guide both libraries and browser development. I'd say we need, the start-stop and often out-of-step (i.e. careful and experimental) shuffle toward standards. WebGL is just the latest waltz, but that visualisation is built on a bunch of foundational standards: TCP, HTTP, HTTPS, OpenGL, WebGL, etc etc

The computers that got us to the moon where highly efficient integrated circuits. But (I presume) they can't get us to mars.

Personally I'd advocate for messy, but rich platforms, which max out our CPUs in some applications; but give expression to the emergent desires of those who want to tinker.

We don't have time to miss-out on potential wins by working with rigid systems.

Earlier quoted context omitted.

The visualisation works fine in newest Firefox on Linux, though only in Chromium do I get the sound effects (like a high pitched fan noise)

Just so that it's clear to other people: The message is in the text of the page, but it does seem to work on a recent version of Firefox.

I'm on Firefox 68.0.1 on Arch and it's not working.

No way, not even close. At this point Google is doing overhead lidar flights to get incredibly details 3d maps. The Planet imagry is like going back several decades in satellite tech. But on the other hand, it's daily.
