Remote sensing of nighttime light

Abstract

Night light observations through remote sensing allow us to make accurate measurements of the location of human activities, so we can in various fields such as urban tracking and economic dynamism, conflict assessment and armed incidents, fisheries study, emission assessment They used greenhouse gases and energy consumption and analyzed light pollution and health effects. New and improved sensors, algorithms, and products for night lights, in conjunction with other ground observations and ancillary data (e.g., geographic location data), have great potential for in-depth understanding of human activities and their environmental consequences. This paper examines the advancement of night light sensors and products, and examines the contribution of night light remote sensing to the perception of a changing world with an emphasis on DMSP / OLS and VIIRS night light data.
