This is absolutely geographic art at its best!

Van Gogh from Space | Massive congregations of greenish phytoplankton swirl in the dark water around Gotland #remotesensing
"Gotland is a Swedish island in the Baltic Sea. (The colors are natural.) Population explosions of phytoplankton occur when deep currents bring nutrients up to sunlit surface waters, fueling the growth and reproduction of the tiny plants." - WSJ
Cruising over the East Coast of North America with #ISS via @geekosystem and @NASA
“The geography buffs out there will certainly enjoy picking out the landmarks as the ISS cruises over the eastern United States on January 29, 2012, from Central America to the bright Northern lights of Newfoundland.”

DARPA’s Spy Telescope Will Stream Real-Time Video from Any Spot on Earth
"While you may not be concerned about Santa Claus spying on you in real-time to find out if you are good or bad, the Pentagon’s research arm intends to make Santa’s naughty or nice magical powers of surveillance look quaint. DARPA is working on a space-based spy telescope that can hover in orbit to "take real-time images or live video of any spot on Earth."

I had been wanting to make this for a while before finding out on Saturday that Mike McCandless had extracted Chrome’s open-source language detector into a standalone library, which suddenly made it much more practical.
There are a lot of near-identical colors for different languages because I was optimizing for maximum distinguishability of languages used near each other rather than for global uniqueness. The exception is English, which is in gray because it is so common almost everywhere that it threw off the process of choosing the other colors.”

Earth from Space via Envisat radar satellite: Indus Valley - #remotesensing -Change detection over several satellite passes.
"This Envisat image shows western India and southern Pakistan, with the Indus River snaking through Pakistan’s Sindh province before emptying into the Arabian Sea. Source: ESA.
This Envisat image shows western India and southern Pakistan, with the Indus River snaking through Pakistan’s Sindh province before emptying into the Arabian Sea.
With a total length of over 3000 km, the river provides key water resources for Pakistan’s people. The area is known for its substantial agricultural base, where cotton, rice, wheat and many kinds of fruit are grown.The Indus River floods its banks during the monsoon season. Last year, particularly heavy rains caused severe flooding that affected millions of people.
The red area in the lower-central portion of the image covers a seasonal salt marsh over Pakistan’s border with western India. During India’s summer monsoon, the area of salty clay fills with standing water, and becomes an important wetland area providing breeding grounds for flamingos.
This image is a compilation of three passes by Envisat’s radar on 15 May, 14 July and 12 September. Each is assigned a colour (red, green and blue) and combined to produce this representation. The colours reveal changes in the surface between Envisat’s passes.” ~ GIS Lounge
