How The Basis Has Changed

Urban Radiance compares historical night-time satellite views of the globe to analyse urban evolution across the world. By comparison recent night-time satellite imagery amongst historical night-time satellite views of the same locations Urban Radiance is able to exhibit how countries convey changed inwards price of urbanization, electrification together with population density.

Urban Radiance has compiled time-based night-time satellite composites of Asia, the Middle East, North America, North Africa, Europe together with the whole World. On each map the newer night-time thought uses orangish to exhibit lite pollution patch the older night-time uses bluish to exhibit lite pollution. In this means it is slow to selection out areas inwards the map where lite pollution has grown over time.

On each composite map Urban Radiance has picked out pregnant areas which convey seen a increase inwards lite pollution. For representative inwards North America Urban Radiance highlights how the increase of shale gas fields inwards the Dakota together with South Texas regions has led to to a greater extent than lite pollution inwards these areas. Below each map graphs exhibit the full increase (or fall) inwards radiance inwards each province shown on the map.
