Ground Settlement
State-of-the-art satellite data processing (Interferometric synthetic aperture radar) has the unique ability of revealing historical ground motion trends over urban areas. The image over Central London shows historical ground and structure motion over a thirteen-year period (1992 – 2005). A linear pattern of settlement associated with the construction of the Jubilee line extension has been revealed. The image to the right can be viewed as an overlay within Google Earth by following this link.

Famous quotes containing the words ground and/or settlement:
“When the ground was partially bare of snow, and a few warm days had dried its surface somewhat, it was pleasant to compare the first tender signs of the infant year just peeping forth with the stately beauty of the withered vegetation which had withstood the winter ... decent weeds, at least, which widowed Nature wears.”
—Henry David Thoreau (1817–1862)
“I always consider the settlement of America with reverence and wonder, as the opening of a grand scene and design in providence, for the illumination of the ignorant and the emancipation of the slavish part of mankind all over the earth.”
—John Adams (1735–1826)
