World, Night, Lights


This layer contains nightime illumination viewed from space around the world. This polygon file is intended for medium to large scale thematic mapping and analysis.



The spatial data were obtained from National Oceanic and Atmospheric Administration Earth Observation Group. The files are cloud-free composites made using all the available archived DMSP-OLS smooth resolution data for calendar years. In cases where two satellites were collecting data - two composites were produced. The products are 30 arc second grids, spanning -180 to 180 degrees longitude and -65 to 75 degrees latitude. The coordinate system of this data is WGS 1984.
