Potentiality of SDGSAT-1 Glimmer Imagery to Investigate the Spatial Variability in Nighttime Lights

International Journal of Applied Earth Observation and Geoinformation, 2023
The successful launch of Sustainable Development Science Satellite 1 (SDGSAT-1) complements the existing nighttime lights (NTL) data with high spatial resolution in the three visible bands (40 m) and the panchromatic band (10 m). This study aimed to evaluate the potentiality of the new NTL imagery – SDGSAT-1 – in revealing the spatial variation in NTL ...

Evaluation of Luojia 1-01 Nighttime Light Imagery for Impervious Surface Detection: A Comparison With NPP-VIIRS Nighttime Light Data

International Journal of Applied Earth Observation and Geoinformation, 2019
Abstract Impervious surface detection is significant to urban dynamic monitoring and environment management. One of the most effective approaches to evaluating the impervious surface is the use of nighttime light imagery. However, little work on this subject was carried out with the new generation nighttime light data from Luojia 1-01 satellite ...

An Approach of Identifying and Extracting Urban Commercial Areas Using the Nighttime Lights Satellite Imagery [PDF]

Remote Sensing, 2020
Urban commercial areas can reflect the spatial distribution of business activities. However, the scope of urban commercial areas cannot be easily detected by traditional methods because of difficulties in data collection. Considering the positive correlation between business scale and nighttime lighting, this paper proposes a method of urban commercial

Population bias in nighttime lights imagery

Remote Sensing Letters, 2019
ABSTRACTBrightness of nighttime lights (NTL) derived from remote sensing imagery has been extensively used to estimate population. However, population bias in NTL images has yet to be investigated. In this study, we explore the associations of race and age demographics with brightness of NTL in the United States (US) for 2015 and 2016.

Summer suburbanization in Moscow Region: Investigation with nighttime lights satellite imagery

Environment and Planning A: Economy and Space, 2022
In the summertime, many Moscow residents move to second homes in the countryside, which causes strong seasonal fluxes in the population size of the Russian capital, its surroundings, and more remote rural areas. To better understand the spatial scale and patterns of seasonal suburbanization, we tracked the changes in average monthly nighttime light ...

A Nighttime Lights Adjusted Impervious Surface Index (NAISI) With Integration of Landsat Imagery and Nighttime Lights Data From International Space Station

International Journal of Applied Earth Observation and Geoinformation, 2019
Abstract Accurate mapping of impervious surface is essential for both urbanization monitoring and micro-ecosystem research. However, the confusion between impervious surface and bare soil is the major concern due to their high spectral similarity in optical imagery.

Improving Nighttime Light Imagery With Location-Based Social Media Data

IEEE Transactions on Geoscience and Remote Sensing, 2019
Location-based social media have been extensively utilized in the concept of “social sensing” to exploit dynamic information about human activities, yet joint uses of social sensing and remote sensing images are underdeveloped at present. In this paper, the close relationship between the number of Twitter users and brightness of nighttime lights (NTL ...
