Cities from Space
At night however, city lights present the space observer spectacular evidence of our existence, our distribution, and our ability to change our environment
The Registered Cities List is a complete list of the images of cities that are registered, or geometrically corrected, and tweaked to match a map of the cities with even scale.
The research presented here is primarily focused on the physical properties of a wide range of urban environments using passive measurement of optical reflectance and thermal emission as well as optical emission of nighttime lights.
Comparative analyses of urban reflectance (visible and infrared color) and surface temperature allow us to develop robust criteria for distinguishing urban land cover from non-anthropogenic land covers.
