Here we present an updated map of night sky brightness. Model that was used to create this map was originally created by Berry and then was improved in our published work. We used high resolution population raster provided by the GHSL. To model night sky brightness we used each cell of raster map as a single light source. This is a new map created in a more reliable way. We included information about topography using Digital Elevation Model (DEM). Additionally we used genetic algorithm to obtain reliable parameters of the model. The resultant map has resolution of 100m.
More information about the model are in the paper:
This solution was also presented during the following conferences:
The software - darksky - that was used for calculations is available here.
