Summary

This dataset contains RAW night-time imagery recorded using a Digital Single-Lens Reflex (DSLR) camera during a survey of artificial light in night-time environments across Exeter, UK between February and May 2023. This dataset comprises the CR2 imagery and information logs. The DSLR camera was setup on a tripod at each location. High Dynamic Range (HDR) imagery was taken in each cardinal direction, as well as a final photo towards zenith. The locations were chosen via randomly selecting roads through stratified random sampling of land use classes. We made each draw in a round-robin manner in quadrants of the city to ensure that they were also spatially well distributed. This data was collected by fieldworkers at the University of Exeter (primarily Sam Morrell and Maisy Inston) to process into flux-calibrated 360 degree maps of the lighting environment across the city.
