Global Spatial Analysis of Urban Night Lights
Global spatial analysis of 1992/93, 1994/95 and 2000 DMSP night lights
suggests consistent scaling across a wide range of city sizes. Comparison
with Landsat 7 imagery in 17 cities worldwide quantifies spatial extent of
overglow and no consistency in frequency detection threshold area reduction.
Comparison with island periphery overglow suggests a quasilinear relationship
between illuminated area and lateral extent of overglow. Details in:
