Caption

First land images from Reaktor Hello World overlaid over image data from Google Earth. This image was taken above Sahara, near the borders of Libya, Egypt and Sudan. The fields in the upper right-hand corner of the image are part of an irrigation experiment. The reddish close-up image measures the spectral signature of water, which enables visualizing the changing moisture content in the ground. The image reveals differences of water content in the fields: the blue-green parts indicate better irrigation, whereas the yellow-orange signify drier conditions.
