Most of Los Angeles is visible in this computer-generated, north by northeast perspective taken from above the Pacific Ocean. In the foreground, the hilly Palos Verdes Peninsula lies to the left of Long Beach Harbor. Farther back sit the various communities that comprise the greaterLos Angeles area. They appear as shades of gray and white. In the distance, the San Gabriel Mountains riseup to separate the Los Angeles Basin from the Mojave Desert, which can be seen near the top of the image.
This 3-D perspective view was generated using topographic data from the Shuttle Radar TopographyMission (SRTM) and an enhanced color Landsat 5 satellite image mosaic. Topographic expression isexaggerated one and one-half times.
Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation datamatches the 30-meter (98-foot) resolution of most Landsat images and will substantially help inanalyzing the large and growing Landsat image archive.
Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboardthe Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument thatcomprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flewtwice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of theEarth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast,installed additional C-band and X-band antennas, and improved tracking and navigation devices. Themission is a cooperative project between NASA, the National Imagery and Mapping Agency(NIMA) of the U.S. Department of Defense and the German and Italian space agencies. It is managed byNASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Earth Science Enterprise, Washington,D.C.
