Improved Denoising of VIIRS Nighttime Light Imagery for Estimating Electric Power Consumption

IEEE Geoscience and Remote Sensing Letters, 2020
Background noise of nighttime light (NTL) imageries derived from the Visible Infrared Imaging Radiometer Suite (VIIRS) day/night band (DNB) adversely affected the accuracy in investigating socio-economic activities, which needed to be reduced. The threshold method was often used in noise reduction, and the critical issue of which was how to determine ...

A Saturated Light Correction Method for DMSP/OLS Nighttime Satellite Imagery

IEEE Transactions on Geoscience and Remote Sensing, 2012
Several studies have clarified that electric power consumption can be estimated from the Defense Meteorological Satellite Program/Operational Linescan System (DMSP/OLS) stable light imagery. As digital numbers (DNs) of stable light images are often saturated in the center of city areas, we developed a saturated light correction method for the DMSP/OLS ...

Correcting the Pixel Blooming Effect (PiBE) of DMSP-OLS Nighttime Light Imagery

Remote Sensing of Environment, 2020
Abstract In the last two decades, the advance in nighttime light (NTL) remote sensing has fueled a surge in extensive research towards mapping human footprints. Nevertheless, the full potential of NTL data is largely constrained by the blooming effect.

These Lit Areas Are Undeveloped: Delimiting China’s Urban Extents From Thresholded Nighttime Light Imagery

International Journal of Applied Earth Observation and Geoinformation, 2016
Abstract Nighttime light imagery is a powerful tool to study urbanization because it can provide a uniform metric, lit area, to delimit urban extents. However, lit area is much larger than actual urban area, so thresholds of digital number (DN) values are usually needed to reduce the lit area. The threshold varies greatly among different regions, but

Detection of Multidimensional Poverty Using Luojia 1-01 Nighttime Light Imagery

Journal of the Indian Society of Remote Sensing, 2020
Poverty is a complex social problem, and accurate poverty identification is a key step for creating strategies to eliminate poverty. The Luojia 1-01 satellite is part of a new generation of professional nighttime light remote sensing that was successfully launched on July 2, 2018, and has provided 130-m high-resolution nighttime light images for ...

Monitoring the electric power consumption by lighting from DMSP/OLS nighttime satellite imagery

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
In this study, we attempted to estimate the electric power consumption using the Defense Meteorological Satellite Program (DMSP)/Operational Linescan System (OLS) stable light imagery after correction for saturation effected. Digital numbers (DNs) of a stable light image are saturated in the center of city areas.

Estimating the energy consumption with nighttime city light from the DMSP/OLS imagery

2009 Joint Urban Remote Sensing Event, 2009
A methodology is presented to accurately estimate electric power consumption from saturated nighttime DMSP/OLS imagery using a stable light correction. An area correction for the stable light image of DMSP/OLS for the year 1999 was performed and the building area rate data were used to clarify the intensity distribution characteristics of the stable ...
