Assessing Light Pollution in China Based on Nighttime Light Imagery [PDF]

Remote Sensing, 2017
Rapid urbanization and economic development inevitably lead to light pollution, which has become a universal environmental issue. In order to reveal the spatiotemporal patterns and evolvement rules of light pollution in China, images from 1992 to 2012 were selected from the Defense Meteorological Satellite Program Operational Linescan System (DMSP/OLS)

Shedding Light on the Shadow Economy: A Nighttime Light Approach

The Journal of Development Studies, 2016
AbstractMeasuring the shadow economy is inherently difficult, but critical for understanding economic development. Using census data on formal and informal sectors in Cambodia, we document that 96.6 per cent of non-farm establishments do not formally register with the government, and their sales accounted for 76.6 per cent of total sales in 2011 ...
