DMSP/OLS night-time lights imagery and urban population estimates in the Brazilian Amazon
The Brazilian Amazon occupies 5 million km and comprehends the largest preserved and continuous tropical rain forest in the world: a forested area of approximately 4 million km. In the last decades, the region has experimented intense transformation processes both in the physical and human aspects. Deforestation studies estimated a rate of 25 400 km of forest conversion for 2001 to 2002 period ...
متن کاملSpatial analysis of global urban extent from DMSP-OLS night lights
Previous studies of DMSP-OLS stable night lights have shown encouraging agreement between temporally stable lighted areas and various definitions of urban extent. However, these studies have also highlighted an inconsistent relationship between the actual lighted area and the boundaries of the urban areas considered. Applying detection frequency thresholds can reduce the spatial overextent of l...
متن کاملDMSP-OLS Radiance Calibrated Nighttime Lights Time Series with Intercalibration
The Defense Meteorological Satellite Program-Operational Linescan System (DMSP-OLS) stable lights products are made using operational OLS data collected at high gain settings, resulting in sensor saturation on brightly lit areas, such as city centers. This has been a paramount shortcoming of the DMSP-OLS stable lights time series. This study outlines a methodology that greatly expands the dynam...
متن کاملDMSP/OLS night-time light imagery for urban population estimates in the Brazilian Amazon
This article analyses DMSP/OLS night-time imagery as an information source to detect human settlements and to estimate the urban population in the Amazon region. DMSP/OLS single orbits were used to generate a DMSP stable light mosaic for 2002, in which most of the urban settlements with a population higher than 5000 inhabitants were precisely identified. DMSP/OLS night-time mosaic images from 1...
متن کاملComparative Estimation of Urban Development in China's Cities Using Socioeconomic and DMSP/OLS Night Light Data
China has been undergoing a remarkably rapid urbanization process in the last several decades. Urbanization is a complicated phenomenon involving imbalanced transformation processes, such as population migrations, economic advancements and human activity dynamics. It is important to evaluate the imbalances between transformation processes to support policy making in the realms of environmental ...
