Abstract
Photographs of the lights seen from outer space at night are a valuable source of freely available online information of city light distribution. Here we take advantage of recently available imagery from the International Space Station (ISS), which provides night-time high resolution images of most cities at Earth. We perform a multifractal analysis of night lights patterns of some of the largest and most populous cities in the World, searching for valuable information of city light spatial distribution. We calculate the fractal dimension, multifractal spectral width, and multifractal spectral range. Then we correlate these fractal parameters with three city characteristics: light pollution, crime index, and quality of life index. And we find a clear relationship between multifractality and the index of quality of life.
