Summary
[edit]DescriptionCity of Dubai at Night, United Arab Emirates.jpg |
English: Orange sodium vapour lights trace the major highways and street grid in and around the metropolitan area, while grey-white mercury vapour lamps fill in the commercial and residential areas. The lighted islands and peninsula of Palm Jumeirah are clearly visible along the coastline. A spiral pattern of lights on the south-eastern fringe of the urban area is a camel racetrack. Night-time images like these are useful to climate modellers, urban planners, and geographers as they allow for simple definition of urban (densely lit) and rural (sparely lit) areas.
