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.

Now working for me on Mozilla/5.0 (Windows NT 10.0; rv:68.0) Gecko/20100101 Firefox/68.0. Sats are spinning around a globe, but scanned area does not appear. Works fine on Edge but it's screen reader can't handle the companion article.

Chromium doesn't have all that tracking stuff right. What's wrong with it?

Not true. Chromium talks a lot to Googles servers. Additionally, "websites" that are made for chrome drive even more people into this monoculture which is bad for the web.

Monoculture was bad when it was IE6, it's good when it's google. At least that's the SV Groupthink.

Telemetry, probably; imagery, definitely not. (They sell this imagery, it's not public information like NOAA data.)

Do you mean that imagery can't be received for some technical reason (like being encrypted) or that it would be illegal to save it as it's copyrighted?

The former - encryption is cheap and lost revenue is expensive.

This is what it usually means when something is "Chrome-only" - developers like me usually try to stick to standards, but don't have the time or resources to do thorough testing of more than one browser. If it works on Firefox, that's gravy (and my current project does, from a cursory check), but I can't guarantee it in the same way that I can for Chrome.

i.e. this particular dev probably tried it on Firefox/Linux, or got bug reports, and just decided to put up a disclaimer.

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

I'm also on 68.0.1 on Arch and it's working for me, so possibly a plugin is interfering.

"Omega tau" made a really nice podcast a while ago about how Planet Labs is approaching Earth observation. That podcast goes into the details how the company and the satellite constellation came to be and what novel approaches they're using. Definitely worth listening: http://omegataupodcast.net/204-earth-observation-at-planet-l...

This is fascinating - especially the talks about the advantages of using COTS electronics.

Once upon a time, the latest and greatest in electronics was produced by military, scientific, and spaceflight applications, with commercial uses being spinoffs that were often up to a decade behind. Now the situation is reversed; consumer electronics are where the innovation is happening, and military/space systems are finding ways to repurpose that technology.

And if an aircraft flies over your property you could get charged with a federal offense (pointing a laser at an aircraft).

Ehhhh, the aircraft flew into the trajectory, are there no other comparable scenarios where there's an intersection that can happen accidentally?

Basically, if you're planning on pointing a laser into the sky, you need at a minimum issue a NOTAM to inform aviators of the hazard. Things like outdoor concerts and some weather observation systems do this.

But... Sending a laser into the sky and intersecting an aircraft that was operating per regulation? That's on the laser-er, and "creating a hazard to aviation" is not a charge that you'll be happy dealing with in many countries.

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)

Both Bing and Google use aerial imagery with centimetre-scale resolution (certainly 25cm). PlanetScope is 3m I think, the totally free stuff like Sentinel 2 is 10m (5 day revisit). The best commercial imaging satellites are <0.5m. Below that it's simpler to use aircraft.
