("In 52 seconds, a shoebox-size satellite covers the distance from Los Angeles to Las Vegas and captures high-resolution photos of the beaches, freeways, mountain, and deserts 250 miles below. With More than 50 such satellites, Planet Labs, a San Francisco startup founded in a garage by former NASA engineers, now has one of the largest-ever imaging fleets aloft, each orbiting the globe every 90 minutes. Together they can photograph most of the planet every day. Embedded in the terabytes of photos the satellites beam to earth are clues to the global economy. * * * [Eg] Satellite images of activity at 6,000 Chinese factories are being translated into a new manufacturing index”)
Note:
(a) summary underneath the title in print: Tiny, cheap satellites will orbit the globe recording everything
(b) Text of the online report is substantially edited for print.
(c) The print has just one photo (the top one online), whose (print) legend reads,
“These images show [‘online: are a composite of’] oil storage facilities oil storage facilities around the globe. Crude is stored in massive tanks whose capacity can be estimated from the shadows they cast. How full [online: ‘much’] is stored can be gauged from the shadows on the interior lids, which move up and down based on the amount of oil in the tank.”
* storage tank
https://en.wikipedia.org/wiki/Storage_tank
(“In the USA, storage tanks operate under no (or very little) pressure, distinguishing them from pressure vessels. Storage tanks are often cylindrical in shape, perpendicular to the ground with flat bottoms, and a fixed or floating roof”/ Above ground or underground)
Another Wikipedia page (for the same things but under the title “oil terminal”) says this is “a comparatively unsophisticated facility.”
