Remote sensing of night light emissions in the visible band offers a unique opportunity to directly observe human activity from space, extending the use of remote sensing to the social sciences. This has allowed a host of applications including mapping urban areas, estimating population and GDP, monitoring disasters and conflicts. More recently, remotely sensed night lights data have found use in understanding the environmental impacts of light emissions (light pollution), including its impacts on human health.
In this talk, Professor Levin will outline the historical development of night-time optical sensors up to the current state of the art sensors, highlight various applications of night light data and discuss the special challenges associated with remote sensing of night lights.
