From: Mapping behaviorally relevant light pollution levels to improve urban habitat planning
Behaviorally relevant levels of photopollution are found across the city and many smaller greenspace patches are completely affected by behaviorally relevant illumination levels. This map combines data from the city of Chicago showing urban greenspaces with areas estimated to be ≥ 6 lux, based on regression tree models fit on ground-level control points using ISS imagery.
