Data and Metadata

The high spatial resolution multi-spectral night-time light remote sensing imagery is collected by the Chinese commercial satellite - Jilin1-03 (JL1-3), which integrates the advantages of space-borne and air-borne night-time light sensors. JL1-3 enables to capture night-time light images in spatial resolution less than 1 m with three spectral bands including 430–512 nm (blue), 489–585 nm (green), and 580–720 nm (red) in 8-bit depth. JL1-3 data have been used in studies such as land use mapping, light source identification, socioeconomic activities, etc. UBDC's night-time images of Glasgow were obtained in December 2021 and Edinburgh images were obtained in January 2022.

Data can be used for various research topics such as the nighttime activities, urbanization, light pollution, etc.

Access and Restrictions

Data are available for non-commercial, academic research by UK-based academics under an End User Licence.
