| Description |
This three-dimensional image of the San Fernando Valley, California was created with data from NASA's Airborne Synthetic Aperture Radar (AIRSAR). Topographic heights were generated using radar interferometry, a technique that combines two radar images to simulate this perspective view. The promient dark features are the runways of the Van Nuys (dark line in the valley center) and the Burbank airports (V shape along right/east side of valley). The Santa Monica Mountains that separate the valley from Los Angeles are shown near the bottom of the image. This type of high-resolution topographic map can provide important information (like what?) to urban planners. The elevations range from 100 to 2000 meters (330 to 6600 feet). Colors correspond to topographic heights above sea level with white being the highest and purple the lowest. This elevation information is draped over a radar image. Overall, the elevations in the image range from 300 to 2000 meters (990 to 6600 feet) above sea level. These data were collected in early June 1996. ##### |
