A recent article in Ecological Economics describes a potentially valuable new data source for studying the spatial patterns of economic activity that may have an impact on regional sustainability. Using night-time lights remote sensing data, which correlates closely with gross regional product, Christopher Doll and colleagues utilize this data set to map a surrogate of economic activity at 5-km resolution. These results provide the first detailed examination of night-time light characteristics with respect to local economic activity and highlight issues, which should be considered when undertaking such analysis.
