Urban Night-time Lights Monitoring Using VIIRS Dataset in Google Earth Engine

Описание: In this video, we explore how to monitor urban night-time lights using the VIIRS Day/Night Band dataset in Google Earth Engine. The tutorial begins by loading administrative boundaries and selecting a study area based on a sample point, then Centering and displaying it on the map. We create a function to process monthly VIIRS radiance data, filter it by year, and compute the annual mean brightness for the study area. Along the way, we apply a custom color palette for visualization, calculate summary statistics such as mean, minimum, and maximum radiance, and print them to the console for analysis. The workflow also includes exporting the annual mean night lights map to Google Drive for further use. Finally, we demonstrate the process for two different years, 2013 and 2023, allowing easy comparison of night time illumination patterns over time. This approach is ideal for analyzing urban growth, economic activity, and light pollution using satellite-based night lights data.
