How Geospatial Technologies Are Being Used to Study Light Pollution
Light pollution is considered to be artificial or anthropogenic introduction of light in what would normally be a night setting. Light pollution has grown significantly throughout the twentieth century as cheap, constant light became more possible in urban areas. However, light pollution has the potential to negatively affect our health, […]
