A new source for high spatial resolution night time images — The EROS-B commercial satellite

摘要: Abstract City lights present one of humankind's most unique footprints on Earth as seen from space. Resulting light pollution artificial obscures the night sky for astronomy and has negative impacts biodiversity well human health. However, remote sensing studies to date have been mostly limited coarse spatial resolution sensors such DMSP-OLS. Here we a new source high mapping space, derived commercial satellite. We tasked Israeli EROS-B satellite acquire two night-time images (at 1 m) Brisbane, Australia, analyzed their radiometric quality content with respect land cover use. The distribution imaged by corresponded acquired an airborne camera, although was not sensitive low levels. Using use data at statistical local area level, could statistically explain 89% variability in lights. Arterial roads service areas were found be some brightest types. Overall, that imagery provides fine lights, opening avenues studying cities worldwide.
