Description: The Very Large Array Observatory, 130km southwest of Albuquerque, New Mexico. It consists of 27 independent radio antennae, each 25m in diameter and 230t in weight. These dishes are on a y-shaped track, each arm is 21km long.
The Overlays are taken from NASA World Wind. Try this competition product by yourself. The resolution is mostly substantially worse than Google Earth and mostly in b/w, too. But you can use for the areas that not much featured in GE, but I guess that is only valid for USA. But one thing is great: NASA World Wind contains an relatively high resolution topographic map and one of the moon. But a least it is no really alternative solution by now. |
