I have always hoped that someday Google Earth would just be live.

That day any notion of privacy will stop existing.

Unless you, I don't know, go inside?

Its already assumed that there is little or no privacy in public spaces.

Check this out: http://www.jma.go.jp/en/gms/largec.html?area=6&element=1&tim... edit: The largest image resolution seems to be 800x800 (well, 800x815, with the attribution footer). I wonder if the new satellite's imagery isn't part of this feed yet? I hope that's the case, because it would be incredibly cool to be get such high-res images.

I hope that they upload the images to some server that we can grab and make animations with. I can watch this all day.

A daily youtube video would be cool. I used to do that with construction webcams.

These are great! I've been looking for something like this for a long time and I could never find anything out of NOAA that had this kind of time resolution. Here about a big storm on the east coast? What does it look like from space? Gotta wait to see whether someone will do a press release.

You might find http://realearth.ssec.wisc.edu/ useful. Just be sure to click on either the "Presets" or "All" tabs within the "Layers" section.

Oh, and if you decide to use the animation feature just try to be patient with the way it loads in the individual times--once you've pulled down everything the animation should look a good bit nicer.

I find that we can do this sort of thing amazing. However on the animation the fact that the terminator line changes angles is a bit unnerving.

It shouldn't be.

I wrote a simple shell script[0] to scrape and output the latest image.

It uses the tiles from their online satellite map[1], and can output images in increments of 1x1, 2x2, 4x4, 16x16 tiles (each tile being 550px by 550px). Here is an example with 2x2 [2]

If you have any suggestions or bugfixes, feel free to fork or comment.

EDIT: Also works for a single tile[3], also clarity.

Privacy is on a sliding scale. There are certain assumptions we rely on when we go out in public.

Imagine, for example, some future where you were effectively under constant surveillance when in "public". Where your every action, every movement, every utterance was recorded, categorized, transcribed, data mined, and then put into a feed that anyone could subscribe to. That's what the complete absence of public privacy looks like, and it's not great.
