How do you map the expansion of Earth's earliest civilizations? For years, researchers have tackled this daunting task on a settlement-by-settlement basis, searching for clues in mounds of earth throughout the Middle East.
But now, researchers have turned to satellite imagery to uncover a vast network of over 14,000 long-overlooked Mesopotamian settlements, spanning 8,000 years of ancient civilization. Their findings represent a monumental step forward for the fields of archeology and anthropology, and suggest that an aerial perspective may hold the key to unlocking the mysteries of humanity's first major settlements.
"[This is] a way to make sure that government planners know to take [these settlements] into consideration when making decisions about future development and modernization, which can be quite destructive to the traces of the past," says Ur. Many regions of the Middle East, he explains, have been understudied by archaeologists, which puts them at risk of being wiped from existence altogether.

Can someone dumb down the second picture and explain it to me? I have a theory.
Edit: most notably the weblike structure. What is that?edit on 27-3-2012 by WordsAreAvenues because: (no reason given)
A multispectral image is one that captures image data at specific frequencies across the electromagnetic spectrum. The wavelengths may be separated by filters or by the use of instruments that are sensitive to particular wavelengths, including light from frequencies beyond the visible light range, such as infrared. Spectral imaging can allow extraction of additional information the human eye fails to capture with its receptors for red, green and blue. It was originally developed for space-based imaging.
Multispectral images are the main type of images acquired by remote sensing (RS) radiometers. Dividing the spectrum into many bands [snip]
This technology has also assisted in the interpretation of ancient papyri, such as those found at Herculaneum, by imaging the fragments in the infrared range (1000 nm). Often, the text on the documents appears to be as black ink on black paper to the naked eye. At 1000 nm, the difference in light reflectivity makes the text clearly readable. It has also been used to image the Archimedes palimpsest by imaging the parchment leaves in bandwidths from 365-870 nm, and then using advanced digital image processing techniques to reveal the undertext of Archimedes work.
The availability of wavelengths for remote sensing and imaging is limited by the infrared window and the optical window.
Spectral band usage:
The wavelengths are approximate; exact values depend on the particular satellite's instruments:
Blue- 450-515..520 nm, is used for atmospheric and deep water imaging, and can reach within 150 feet (50 m) deep in clear water.
Green- 515..520-590..600 nm, is used for imaging of vegetation and deep water structures, up to 90 feet (30 m) in clear water.
Red- 600..630-680..690 nm, is used for imaging of man-made objects, in water up to 30 feet (9 m) deep, soil, and vegetation.
Near infrared- 750-900 nm, is used primarily for imaging of vegetation.
Mid-infrared-1550-1750 nm, is used for imaging vegetation, soil moisture content, and some forest fires.
Mid-infrared- 2080-2350 nm, is used for imaging soil, moisture, geological features, silicates, clays, and fires.
Thermal infrared-10400-12500 nm, uses emitted radiation instead of reflected, for imaging of geological structures, thermal differences in water currents, fires, and for night studies.
Radar and related technologies are useful for mapping terrain and for detecting various objects.
Planetary Energetic Grid Theory falls under the heading of pseudoscience. It operates through geometric patterns called Sacred Geometry. Grids meet at various intersecting points forming a grid or matrix. This is equivalent to the acupressure points on our bodies. These grid points can be found at some of the strongest power places on the planet.
Plato recognized grids and their patterns, devising a theory that the Earth's basic structure evolved from a simple geometric shapes to more complex ones. These shapes became known as platonic solids: cube (4), tetrahedron (3), octahedron (8), dodecahedron (12), icosahedron(20). In Timeaus, Plato associated each shape with one of the elements, earth, fire, air, ether, and water. The Earth's energy grids, from the beginnings of its evolutionary course, has evolved through each of these shapes to what it is today. Each shape, superimposed, one upon the other to create a kind of all encompassing energy field that is the very basis of Earth holding it all together.
