Development of a 2009 Stable Lights Product using DMSP-OLS data [PDF]

Proceedings of the Asia-Pacific Advanced Network, 2010
Since 1994, NGDC has had an active program focused on global mapping of nighttime lights using the data collected by the Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) sensors.  The basic product is a global annual cloud-free composite, which averages the OLS visible band data for one satellite from the cloud-free ...

Intercalibration of DMSP-OLS night-time light data by the invariant region method

International Journal of Remote Sensing, 2013
DMSP-OLS Defense Meteorological Satellite Program Operational Linescan System night-time light data can accurately reflect the scope and intensity of human activities. However, the raw data cannot be used directly for temporal analyses due to the lack of inflight calibration. There are three problems that should be addressed in intercalibration. First,

A Simulation Study on the Urban Population of China Based on Nighttime Light Data Acquired from DMSP/OLS

Sustainability, 2016
The urban population (UP) measure is one of the most direct indicators that reflect the urbanization process and the impacts of human activities. The dynamics of UP is of great importance to studying urban economic, social development, and resource ...

Studies on forest fires using dmsp ols data

Journal of the Indian Society of Remote Sensing, 1999
Studies related to forest fires are important in the context of trace gas emissions associated with such events. Much of the polar orbiting satellites due to their repetitive cycle have limitation in observing such events and in tropics due to cloud cover, the chance of getting cloud free image during day time becomes difficult. In order to explore the

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 ...

Monitoring of the human activities from DMSP/OLS nighttime imageries

2019
Here, we illustrate the use of Defence Meteorological Satellite Program-Operational Linescan System (DMSP/OLS) night-time imageries as a dataset to monitor human activities and urban change at regional scale. With the new approach, Compounded Night Light Index (CNLI) was extracted from DMSP/OLS imageries and this process was applied in a special time ...

Examining Urbanization Dynamics in Turkey Using DMSP–OLS and Socio-Economic Data

Journal of the Indian Society of Remote Sensing, 2018
The present study tried to determine the spatial expansion of urban areas in all the cities in Turkey and to examine the relationship between this spatial expansion with the related demographic, employment, educational, industrial and other indicators using the Geographical Information Systems. The present study was made up of three parts. In the first

Intercalibration of DMSP/OLS by Parallel Regressions

IEEE Geoscience and Remote Sensing Letters, 2016
The Defense Meteorological Satellite Program—Operational Linescan System night lights offer a unique data set, covering more than two decades. However, for a number of reasons, an intercalibration procedure has to take place in order to reduce year-to-year inconsistencies before a meaningful time series can be established.
