Mergui Archipelago

nobody@flickr.com (NASA Goddard Photo and Video) — Mon, 03 Dec 2012 07:39:39 -0800

NASA Goddard Photo and Video posted a photo:

NASA image acquired December 14, 2004

In the southernmost reaches of Burma (Myanmar), along the border with Thailand, lies the Mergui Archipelago. The archipelago in the Andaman Sea is made up of more than 800 islands surrounded by extensive coral reefs.

This natural color image acquired by Landsat 5 on Dec. 14, 2004, shows the middle portion of the archipelago, including Auckland and Whale Bays. Swirling patterns are visible in the near-shore waters as sediments carried by rivers slowly settle out and are deposited on the seafloor. The heavy sediment loads make the river appear nearly white. As those sediments settle out, the seawater appears deeper shades of blue. The tropical rainforests of the region appear deep green.

Captain Thomas Forrest of the East India Company first described the region to Europeans after a 1782 expedition in search of potential sugar-growing lands. At that time, the islands were mainly inhabited by a nomadic fishing culture. These people, known as the Moken, still call the archipelago home and mostly live a hunter-gatherer lifestyle. As of 2006, 2,000 Moken were known to inhabit the Burmese portion of Mergui.

The small population of the archipelago has helped preserve its high diversity of plants and animals. In 1997, Burma opened the region to foreign tourism and in the years since it has become a major diving destination. A valued species of pearl oyster (Pinctada maxima) are found in nearby waters. Today, overfishing is emerging as a regional problem.

The U.S. Post Office released on Oct. 1 a series of 15 Earthscapes Forever stamps that depict America's diverse landscapes viewed from aerial and satellite perspectives. Taken from heights of several hundred feet above Earth to several hundred miles up in space, the images on the stamps provide a new perspective on the world we live in.

"Once you've seen the world from above, you never look at it quite the same way again," said Joseph Corbett Postal Service chief financial officer and executive vice president . "That's why the Postal Service is proud to offer these Earthscapes stamps, which invite us to take a bird's-eye view of the land we all share."

The stamps present examples of three categories of Earthscapes: natural, agricultural and urban. The images were all taken high above the planet's surface, either carefully composed by photographers in aircraft or snapped by satellites orbiting Earth.

"For nearly 50 years, NASA has been at the forefront of looking at Earth from the unique vantage point of space," said Chris Scolese, center director at NASA's Goddard Space Flight Center in Greenbelt, Md., where the stamps were unveiled.

NASA Goddard Photo and Video posted a photo:

Over the years of the Landsat program, the desert city of Las Vegas has gone through a massive growth spurt. The outward expansion of the city over the last quarter of a century is shown here with two false-color Landsat 5 images (August 3, 1984, and November 2, 2011). The dark purple grid of city streets and the green of irrigated vegetation grow out in every direction into the surrounding desert. These images were created using reflected light from the shortwave infrared, near-infrared, and green portions of the electromagnetic spectrum (Landsat 5 TM bands 7,4,2).

NASA and the U.S. Department of the Interior through the U.S. Geological Survey (USGS) jointly manage Landsat, and the USGS preserves a 40-year archive of Landsat images that is freely available over the Internet. The next Landsat satellite, now known as the Landsat Data Continuity Mission (LDCM) and later to be called Landsat 8, is scheduled for launch in 2013.

In honor of Landsat’s 40th anniversary in July 2012, the USGS released the LandsatLook viewer – a quick, simple way to go forward and backward in time, pulling images of anywhere in the world out of the Landsat archive.

Landsat View: Tokyo, Japan

nobody@flickr.com (NASA Goddard Photo and Video) — Mon, 13 Aug 2012 13:08:31 -0700

NASA Goddard Photo and Video posted a photo:

Tokyo is the world’s largest metropolitan region, home to nearly 37 million people. During the past two decades, Tokyo’s population has grown by more than 7 million. The city’s growth has continued despite Japan’s overall stagnating population, mainly due to a continued trend of centralization—citizens moving out of the country and into the city.

Landsat 4 collected this first false-color image of Tokyo on Feb. 2, 1989. The upper half of Tokyo Bay is the large water body visible in a dark blue. In the middle of the image, central Tokyo appears a deep purple just north of the bay. Twenty-two years later, Landsat 5, captured this second image of Tokyo on April 5, 2011. The urban reaches of metropolitan Tokyo have grown in both distance and density, as seen where the green color of vegetation has turned to pink and purple shades of urbanization. A major expansion of Tokyo’s Haneda Airport, can be seen south of the city, on land built out into the bay. The constant circular spot of green in the dense city-center, visible on both images, is the Tokyo Imperial Palace and its gardens. (Landsat 5 TM Bands 7,4,2)

Santiago, Chile, ranks among the world's fastest growing cities. Chile is South America's fifth largest economy with strong export and tourism markets. More than a third of Chile's population lives in Santiago as of 2009. Taken on January 9, 1985, and January 30, 2010, this pair of images from the Landsat 5 satellite illustrates the city's steady growth. The images were made with infrared and visible light (Landsat bands 4, 3, and 2) so that plant-covered land is red. Bare or sparsely vegetated land is tan, and the city is dark silver. In the fifteen years that elapsed between 1985 and 2010, the city expanded away from the Andes Mountains along spoke-like lines, which are major roads.

Square grids are agriculture.

By January 10, 2003, when Landsat 7 took this image, the Pearl River Delta was a densely populated urban corridor with several large cities. The urban areas are gray in this image. The region is a major manufacturing center with an economy the size of Taiwan’s. As of 2010, the Pearl River Economic Zone had a population of 36 million people.

NASA Goddard Photo and Video posted a photo:

The landlocked western African nation of Burkina Faso experienced a 200 percent increase in urban population between 1975 and 2000. As a result, the area of the capital city Ouagadougou grew 14-fold during this period.

These Landsat images show the city expanding outward from its center in the two decades between 1986 and 2006. On Nov. 18, 1986, the Landsat 5 satellite acquired this image of the capital. This false-color image shows vegetation in shades of green and gray, water in various shades of blue, and urban areas in pink and purple. The runway of the city’s airport can be seen as a long straight line that extends from southwest to northeast south of the large lake, Bois de Boulogne.

Two decades later, on Oct. 16, 2006 Landsat 7 acquired this image of Ouagadougou. Growth radiated from the city center in all directions. The green strip of vegetation north of Bois de Boulogne has been paved over and a massive new development including a large thoroughfare and traffic circle can be seen south of the airport.

When Landsat 7 imaged Dubai on July 6, 2000, the city was barely visible against the desert landscape. Long straight roads sweep down the coast, and a single harbor juts into the Gulf. Though it seems small in this image, the city was growing quickly as a trade center, oil producer, and member of the United Arab Emirates.

Between 2000 and 2010, Dubai transformed entirely. In this Landsat 7 image, taken on October 6, 2010, dense gray city blocks are surrounded by plant-covered land, which is olive green. Artificial islands dot the coast. Dubai’s growth is built on tourism, trade, and oil.

NASA Goddard Photo and Video posted a photo:

Between 1985 and 2009, the population of Tehran, Iran, grew from six million to just over seven million. The city's growth was spurred largely by migration from other parts of the country. In addition to being the hub of government and associated public sector jobs, Tehran houses more than half of Iran's industry.

Landsat 5 acquired these false-color images of Tehran on August 2, 1985, and July 19, 2009. The city is a web of dark purple lines, vegetation is green and bare ground is pink and tan. The images were created using both infrared and visible light (band combination 7, 4, and 2) to distinguish urban areas from the surrounding desert.

NASA and the U.S. Department of the Interior through the U.S. Geological Survey (USGS) jointly manage Landsat, and the USGS preserves a 40-year archive of Landsat images that is freely available over the Internet. The next Landsat satellite, now known as the Landsat Data Continuity Mission (LDCM) and later to be called Landsat 8, is scheduled for launch in 2013.

In honor of Landsat’s 40th anniversary in July 2012, the USGS released the LandsatLook viewer – a quick, simple way to go forward and backward in time, pulling images of anywhere in the world out of the Landsat archive.

Landsat Data Continuity Mission (LDCM) Observatory Electromagnetic Interference/Electromagnetic Compatibility (EMI/EMC) testing is underway at Orbital Science Corporation's Gilbert, Ariz., location. EMI/EMC testing is conducted in order to validate that while the Observatory is on-orbit in space, all Observatory components (including the instruments) can operate successfully together. After successful EMI/EMC testing, the Observatory will be prepared for a series of mechanical tests next month to validate that the Observatory can survive the launch environment. These images were taken August 7, 2012.
