Abstract |
The Defense Meteorological Satellite System(DMSP) Operational Linescan System (OLS) has a unique low\|light imaging capability developed for the detection of clouds lit by mooolight.In addition to moonlit clouds,the OLS sensor also detects nocturnal lights from the earth surface.Hence,DMSP/OLS night\|time emissions data becomes well known as a means of monitoring human activities.In this paper,we reviewed a number of applications that had been developed or proposed based on the DMSP/OLS night\|time emissions data,such as monitoring city lights,light pollution,fires,fishing boats and gas flare,and estimating socioeconomic data.Finally,the advantages and disadvantages of night light data were listed and more applications are expected in the future based on the available light emission data. |
