NASA : Super View of Glendale and Phoenix .- Súper Vista de Glendale y Phoenix

Hola amigos : A VUELO DE UN QUINDE EL BLOG., la Agencia Espacial NASA, nos informa de una espectacular vista de Glendale y Phoenix, en Arizona,  captada desde la Estación  Espacial Internacional por miembros de la Expedición 35, el 16 de marzo del 2013. Al igual que muchas de las grandes áreas urbanas del centro y oeste de Estados Unidos, la zona metropolitana de Phoenix se presenta a lo largo de una malla regular de manzanas y calles. Si bien visible durante el día, esta red se hace más evidente en la noche, cuando el patrón de iluminación de las calles es claramente visible desde arriba.
En el caso de esta fotografía, desde el punto de vista bajo la órbita de la Tierra de la Estación Espacial Internacional. La forma de cuadrícula urbana fomenta el crecimiento de una ciudad hacia el exterior a lo largo de sus fronteras, proporcionando un acceso óptimo a nuevos bienes inmuebles. Impulsado por la adopción del uso de automóvil personal generalizada durante el siglo 20, el área metropolitana de Phoenix hoy incluye a otros 25 municipios (muchos de ellos en gran parte suburbano y residencial de carácter) unidos por una red de calles de la superficie y autopistas......
 
Super View of Glendale and Phoenix
One of the Expedition 35 crew members on the International Space Station used a still camera with a 400 millimeter lens to record this nocturnal image of the Phoenix, Arizona area on March 16, 2013. Like many large urban areas of the central and western United States, the Phoenix metropolitan area is laid out along a regular grid of city blocks and streets. While visible during the day, this grid is most evident at night, when the pattern of street lighting is clearly visible from above -- in the case of this photograph, from the low Earth orbit vantage point of the International Space Station. The urban grid form encourages growth of a city outwards along its borders, by providing optimal access to new real estate. Fueled by the adoption of widespread personal automobile use during the 20th century, the Phoenix metropolitan area today includes 25 other municipalities (many of them largely suburban and residential in character) linked by a network of surface streets and freeways. The image area includes parts of several cities in the metropolitan area including Phoenix proper (right), Glendale (center), and Peoria (left). While the major street grid is oriented north-south, the northwest-southeast oriented Grand Avenue cuts across it at image center. Grand Avenue is a major transportation corridor through the western metropolitan area; the lighting patterns of large industrial and commercial properties are visible along its length. Other brightly lit properties include large shopping centers, strip centers, and gas stations which tend to be located at the intersections of north-south and east-west trending streets. While much of the land area highlighted in this image is urbanized, there are several noticeably dark areas. The Phoenix Mountains at upper right are largely public park and recreational land. To the west (image lower left), agricultural fields provide a sharp contrast to the lit streets of neighboring residential developments. The Salt River channel appears as a dark ribbon within the urban grid at lower right.
