Description [JSC2000-E-02778 PIA02730 (Release Date: 21 February 21, 2000) --- The San Francisco Bay Area in California and its surroundings are shown in this radar image from the Shuttle Radar Topography Mission (SRTM). On this image, smooth areas, such as the bay, lakes, roads and airport runways appear dark, while areas with buildings and trees appear bright. Downtown San Francisco is at the center and the city of Oakland is at the right, across San Francisco Bay. Some city areas, such as the South of Market district in San Francisco, appear bright due to the alignment of streets and buildings with respect to the incoming radar beam. Three of the bridges spanning the Bay are seen in this image. The Bay Bridge is in the center and extends from the city of San Francisco to Yerba Buena and Treasure Islands, and from there to Oakland. The Golden Gate Bridge is to the left and extends from San Francisco to Sausalito. The Richmond-San Rafael Bridge is in the upper right and extends from San Rafael to Richmond. Angel Island is the large island east of the Golden Gate Bridge, and lies north of the much smaller Alcatraz Island. The Alameda Naval Air Station is seen just below the Bay Bridge at the center of the image. Two major faults bounding the San Francisco-Oakland urban areas are visible on this image. The San Andreas Fault, on the San Francisco peninsula, is seen on the left side of the image. The fault trace is the straight feature filled with linear reservoirs, which appear dark. The Hayward Fault is the straight feature on the right side of the image between the urban areas and the terrain laden with hills to the east. This radar image was acquired by just one of SRTM's two antennas and, consequently, does not show topographic data, but only the strength of the radar signal reflected from the ground. This signal, known as radar backscatter, provides insight into the nature of the surface, including its roughness, vegetation cover and urbanization. The overall faint striping pattern in the images is a data processing artifact due to the preliminary nature of this image product. These artifacts will be removed after further data processing. This image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM uses the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. The mission is designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense (DoD) and the German and Italian space agencies. It is managed by, NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Earth Science Enterprise, Washington, DC. Size: 38 km (24 miles) by 71 km (44 miles) Location: 37.7 deg. North lat., 122.2 deg. West lon. Orientation: North to the upper right Original Data Resolution: 30 meters (99 feet) Date Acquired: February 16, 2000 Image: NASA/JPL/NIMA]

Description STS079-783-026 Baltimore, Maryland, USA September 1996 Downtown Baltimore (center of the picture) is easy to identify as the focal point where numerous highways (light-colored lines) come together. This expansive highway network and the extensive urban area places Baltimore within Megalopolis, one of the world?s largest populated land corridors, extending from Boston (MA) to Richmond (VA). Although the infrastructure of the port facilities can not be observed on this small scale image, the proximity of Baltimore Harbor to Chesapeake Bay illustrates that Baltimore?s economy, at least in part, is tied to the fishing industry as well as seagoing international shipping and commerce. The intersecting runways of Baltimore-Washington International Airport are visible south of the downtown area. Two noted highway bridges are visible: the Francis Scott Key Bridge at the mouth of Baltimore Harbor and the Chesapeake Bay Bridge northeast of Annapolis.

Description STS098-382-0014 (7-20 February 2001) City Lights of the Northeastern Seaboard of the U.S. were captured with a 35mm camera by one of the STS-98 astronauts aboard the Space Shuttle Atlantis. The nighttime scene shows the bright lights of several major cities that span a distance from Connecticut (left middle) to states south of Virginia (right middle). Lights from both very large urban areas as well as smaller towns and cities are visible. The largest cluster of brightness emanates from the greater New York metropolitan area (left center) and then a series of bright spots progress southwesterly to include Philadelphia (PA), Baltimore (MD), Washington (D.C.), Richmond (VA), and finally ending with the Newport News/ Norfolk (VA) lights (top center). Many of the major ground transportation arteries can be seen as radial, linear features that radiate outward from the central business districts of the cities. Even the lights of smaller cities such as Allentown, Reading, Lancaster, York, and Harrisburg (PA) are visible (bottom center).

Description STS098-716-057 (7-20 February 2001) --- Baltimore, Maryland can be identified in this northwest-looking view, photographed with a 70mm handheld camera from the Space Shuttle Atlantis, which shows the western shore of Chesapeake Bay. Numerous drowned river valleys provide excellent natural harbors along the periphery of the bay. Baltimore?s harbor has been developed along one of these drowned valleys, the Patapsco River. With a population of over 2.5 million people, the greater Baltimore urban area is part of the northeastern U.S. Megalopolis that extends from the Boston (MA) area to Richmond (VA). Specific features that can be seen in the image include a short segment of Interstate Highway 95 that connects southwest Baltimore with northeast Washington, D.C.; the intersecting runways of Baltimore-Washington International Airport south of downtown Baltimore; Francis Scott Key Bridge that skirts around the southeast side of Baltimore; the Chesapeake Bay Bridge that spans the bay and connects the Baltimore area with the eastern shore of Maryland; and the central business district of Baltimore where the two arms of the inner harbor terminate. The darker-looking vegetation cover is mixed hardwood forests (notice that many wooded areas are located along streambeds and floodplains of small river valleys), while lighter-looking land parcels in the rural countryside is used for crops or pasturelands.
