Nighttime light data reveal how flood protection shapes human proximity to ri...
To understand the spatiotemporal changes of flood risk, we need to determine the way in which humans adapt and respond to flood events. One adaptation option consists of... -
Correlations between Urbanization and Vegetation Degradation across the World...
Changes in biodiversity owing to vegetation degradation resulting from widespread urbanization demands serious attention. However, the connection between vegetation degradation... -
A time series of urban extent in China using DSMP/OLS nighttime light data
Urban extent data play an important role in urban management and urban studies, such as monitoring the process of urbanization and changes in the spatial configuration of urban... -
Using luminosity data as a proxy for economic statistics
One of the pervasive issues in social and environmental research has been to improve the quality of socioeconomic data in developing countries. Because of the shortcoming of... -
Tracking Electrification in Vietnam Using Nighttime Lights
We report on a systematic ground-based validation of DMSP-OLS night lights imagery to detect rural electrification in Vietnam. Based on an original survey of village-level units... -
Quantitative estimation of urbanization dynamics using time series of DMSP/OL...
Urbanization process involving increased population size, spatially extended land cover and intensified economic activity plays a substantial role in anthropogenic environment... -
The Night Light Development Index (NLDI): a spatially explicit measure of hum...
We have developed a satellite data derived ''Night Light Development Index'' (NLDI) as a simple, objective, spatially explicit and globally available empirical measurement of... -
From wealth to health: modelling the distribution of income per capita at the...
Sub-national figures providing information about the wealth of the population are useful in defining the spatial distribution of both economic activity and poverty within any... -
Monitoring Economic Development from Space: Using Nighttime Light and Land Co...
This study demonstrates estimations of economic activities on global, national, and subnational levels using remote sensing data, with a focus on developing economies. It... -
Why VIIRS data are superior to DMSP for mapping nighttime lights?
For more than forty years the U.S. Air Force Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) has been the only system collecting global low... -
Nighttime lights as a proxy for Human Development at the local level
Nighttime lights, calculated from weather satellite recordings, are increasingly used by social scientists as a proxy for economic activity or economic development in... -
A sharper image? Estimates of the precision of nighttime lights as a proxy fo...
Much aggregate social-science analysis relies upon the standard national income and product accounts as a source of economic data. These are recognized to be defective in many... -
Detecting Urban Markets With Satellite Imagery: An Application To India
We propose a methodology for defining urban markets based on built-up land-cover classified from daytime satellite imagery. Compared to markets defined using minimum thresholds... -
The impact of urban growth on agricultural and rural non-farm growth in Kenya
To estimate the impact of urban growth on agricultural and rural nonfarm income growth we develop an urban gravity variable that reflects the economic activity of a city– total... -
Do refugee camps help or hurt hosts? The case of Kakuma, Kenya
We combine nighttime lights data, official statistics, and new household survey data from northern Kenya in order to assess the impact of long-term refugee camps on host... -
Detecting Zimbabwe’s Decadal Economic Decline Using Nighttime Light Imagery
Zimbabwe’s economy declined between 2000 and 2009. This study detects the economic decline in different regions of Zimbabwe using nighttime light imagery from the Defense... -
Normalization of time series DMSP-OLS nighttime light images for urban growth...
Previous studies demonstrated that DMSP-OLS stable nighttime light data are useful data source for delineating urban areas. However, the nighttime light data acquired in... -
Monitoring hourly night-time light by an unmanned aerial vehicle and its impl...
Satellite-observed night-time light in urban areas has been widely used as an indicator for socioeconomic development and light pollution. Up to present, the diurnal dynamics of... -
A comparison of nighttime satellite imagery and population density for the co...
The striking apparent correlation between nighttime satellite imagery and human population density was explored for the continental United States. The nighttime stable-lights... -
Using Landsat and nighttime lights for supervised pixel-based image classific...
Reliable representations of global urban extent remain limited, hindering scientific progress across a range of disciplines that study functionality of sustainable cities. We...
