Trace the Ancient Civilization via Satellite

Sleuth known since our ancestors alive and hunting moves. Now, this knowledge used to find thousands of traces of human civilization in the past.

Researchers from the two famous universities in the United States tried to find traces of past civilizations. They use images from remote sensing images collected from satellites which are in Earth orbit.

Researchers chose northern Mesopotamian region, which is now the territory of Syria, as the research location. They found traces of human civilization is 9.500 of the past in an area of ​​23 thousand square kilometers.
Archaeologists inspect the mound at Tell Brak, in northeastern Syria. The 283 million cubic foot (8 million cubic meter) mound is entirely artificial, accumulating over 6,000 years, as residents built on top of old mud brick buildings. (Picture from: http://www.cbsnews.com/)
 "This is a satellite imagery-based archaeological survey of the largest ever conducted," said the researchers, anthropologist Jason Ur, Harvard University, in a press release reported by the website LiveScience. Like the independent cities that are built on the present, a small mound was built to form clusters (cluster) settlements on the northern edge of the Fertile Crescent in the year 7000 BC.

Computer experts from the Computer Science and Artificial Intelligence Laboratory Massachusetts Institute of Technology, Bjoern Menze, said the remaining mound civilizations past has not been widely used in the search for human culture. Therefore, the bumps in the surface soil is used as search keys they do.
A black and white photograph takes all of the wavelengths visible to us and blends them together. A color image shows them as combinations of red, green, and blue. Multispectral imagery... can see larger wavelengths like the near-infrared and beyond. The soils atop archaeological sites can be sensitive in both the visible and infrared ranges.

Land also left traces of civilization. Humans who live in the fertile soil will enrich the soil with organic material and convert grains into finer and lighter. Computer algorithms used to recognize these changes. Examination of satellite imagery to deliver them on more than 14 thousand archaeological sites.

When an affluent neighborhood changed, the larger the size of the mound. Residential areas are also increasingly widespread as more and more men are attracted to live in the region. *** [LIVESCIENCE | ANTON WILLIAM | KORAN TEMPO 3829]
