Brazilian Mine Disaster Juxtapose

-20.237096°,-43.421697° - Maxar Technologies

On 5 November 2015, two dams collapsed at an iron ore mine in southeastern Brazil. News outlets estimated that approximately 62 million cubic metres (81 million cubic yards) of toxic waste water (similar to the red mud on previous page) was unleashed. As seen in this Juxtapose, the immediate release of sludge wiped out the village of Bento Rodrigues, resulting in the death of 17 people. Because of this pollution, more than half a million people did not have access to clean drinking water or water to irrigate crops for an extended period of time. Furthermore, within two weeks of the dam rupture, the contaminated waters had spread across a 644-kilometre (400-mile) stretch of the Doce River and entered into the Atlantic Ocean, killing significant amounts of plant and animal life along the way. Officials are concerned that the toxins will continue to threaten the Comboios Nature Reserve, a protected area for the endangered leatherback turtle.

Marabe Al Dhafra

23.611166°,53.706629° - Maxar Technologies

The villas of Marabe Al Dhafra in Abu Dhabi, United Arab Emirates are home to approximately 2,000 people. The yearly average temperature in Abu Dhabi is slightly greater than 94 degrees Fahrenheit (34.5 degrees Celsius).

Detroit Metropolitan Airport (DTW)

42.212500°,-83.353333° - Maxar Technologies

Detroit Metropolitan Airport covers more than 11 square miles in Romulus, Michigan. Concourse A at McNamara Terminal, seen here at left, is the world's second-longest airport terminal building, extending a length of one mile (Kansai Airport in Japan has a 1.7 mile long terminal). Detroit Metro is the 16th busiest facility in the United States, serving more than 32 million passengers each year.

Tarawa

1.416667°,173.033333° - Maxar Technologies

Kiribati is a low-lying island nation in the Central Pacific Ocean. The 102,000 residents of Kiribati may be forced to relocate as increased ice melt causes the Pacific Ocean to rise and submerges its islands. Fiji has boldly offered to take in the people of Kiribati if that occurs. Tarawa, an atoll that serves as the capital of the country and is home to half of it’s population, is seen here.

Vail Ski Resort

39.639100°,-106.373800° - Maxar Technologies

Vail Ski Resort is located in Eagle County, Colorado, USA. Spanning 5,289 acres, Vail is the third largest single mountain ski resort in the United States and has the fourth largest skiable terrain in North America. This particular Overview was luckily captured in October as the foliage on the mountain was changing colors.

Center-pivot irrigation

30.089890°,38.271807° - Maxar Technologies

Center pivot irrigation is used throughout the Wadi As-Sirhan Basin of Saudi Arabia. Water is mined from depths as great as one kilometer (~3,000 ft), pumped to the surface, and evenly distributed by sprinklers that rotate 360 degrees. Spurred by a government effort to strengthen its agriculture sector, cultivated land in Saudi Arabia grew from 400,000 acres in 1976 to more than 8 million acres by 1993. For a sense of scale, the total area shown in this Overview is approximately fifty square miles (32,000 acres).

Salt Ponds

37.495364°,-122.160180° - Maxar Technologies

A recent figure estimates that 80% of the San Francisco Bay wetlands area - approximately 16,500 acres - have been developed for salt mining. The ponds get their particular, vibrant colors from the micro-algae that live there and the species' tolerance to salinity. Areas that have a bright red hue are caused by the algae Dunaliella, which thrives in water with extremely high salt content. For a sense of scale, this Overview shows approximately one half of a square mile.

San Alfonso del Mar

-33.350000°,-71.653333° - Maxar Technologies

The swimming pool at the San Alfonso del Mar Resort in Algarrobo, Chile is the largest in the world. The pool is more than one thousand meters long (3,323 ft) and contains approximately 250 million liters (66 million gallons) of water! The resort pays $4 million dollars each year to maintain the pool.

TAPO Bus Terminal

19.430011°,-99.112300° - Maxar Technologies

To continue my selection of favorite Overviews from 2015, I’m excited to repost this one of the Terminal de Autobuses de Pasajeros de Oriente - a major bus terminal in Mexico City, Mexico. Commonly known as TAPO, the dome-covered structure accommodates more than 10,000 passengers per day traveling to fourteen states throughout the country.

Davis-Monthan Air Force Base

32.171449°,-110.848683° - Maxar Technologies

The largest aircraft storage and preservation facility in the world is located at Davis–Monthan Air Force Base in Tucson, Arizona. The facility - run by the 309th Aerospace Maintenance and Regeneration Group - contains more than 4,400 retired American military and government aircraft.

Cadiz Ranch

34.494638°,-115.500469° - Maxar Technologies

Cadiz Ranch in Essex, California is located in the middle of the Mojave Desert. The organic farm grows lemons, table grapes (dried and turned into raisins) and squash on more than 300 acres of irrigated desert. This is made possible by seven wells that pump 2,000 gallons of water per minute at all times from an underground aquifer - a layer of water-bearing permeable rock from which water can be extracted.

Camps Bay Beach

-33.950000°,18.383333° - Maxar Technologies

Waves break on the rocks by Camps Bay Beach — a beautiful white-sand beach in Camps Bay, a suburb of Cape Town, South Africa. In the summer, many South Africans and tourists flock to this beautiful area of the city.

Kansai International Airport (KIX)

-32.016664°,69.955090° - Maxar Technologies

Kansai International Airport is located on an artificial island in the middle of Osaka Bay, Japan. To create the island, a 30 meter (98-foot) layer of earth was created on top of the seafloor with 21 million cubic meters of landfill. The material was excavated from three separate mountains. As of 2008, the total cost of Kansai Airport was $20 billion USD, including land reclamation that has been necessary to prevent its continued sinkage (7.1 centimeters per year as of 2008) into the bay.

Louvre Museum

48.860854°,2.335812° - Maxar Technologies

A river cruise passes by the Louvre Museum in Paris, France. Located on the Seine River, the Louvre is the world’s most visited museum, receiving more than nine million visitors per year. The entrance to the museum, seen at the top and center of this Overview is a glass and metal pyramid, designed by architect I.M. Pei. Visitors enter through the pyramid, descend into the spacious lobby, and then re-ascend into the wings of the museum.

Las Vegas at night

36.175000°,-115.136389° - NASA

The glowing lights of Las Vegas, Nevada are captured here from the International Space Station. Since the city is entirely surrounded by desert, its brightly lit grid of streets starkly contrasts the dark, undeveloped area on its outskirts. You’ll also notice the Las Vegas Strip - the city’s central avenue that is seen at the middle of this Overview. This particular area is one of the brightest spots on Earth due to the concentration of lights emanating from the hotels and casinos along the road.

Seaweed Farms

-8.695228°,115.441324° - Maxar Technologies

Seaweed farms on Nusa Lembongan – a small island located southeast of Bali, Indonesia – have an average harvest of 50,000 pounds per month. Once the seaweed is extracted from the water, it is dried by the sun for 3-7 days, depending on the season.

Residential Development

31.103526°,-97.769887° - Maxar Technologies

The Great Pyramids of Giza

29.976111°,31.132778° - Maxar Technologies

The Great Pyramids of Giza are located on the outskirts of Cairo, Egypt. Dating back to 2580 BC, the Great Pyramid, the largest structure at the site, is the oldest of the Seven Wonders of the Ancient world and the only one to remain largely intact.
