Prediction of kilometre-level socioeconomic activity. a The rasterised bit map of nighttime light from VIIRS in Greater London, which is pruned by the outliers of the AP distribution (we also set the value of a nighttime light pixel as 0 if there is no population within it). b The predicted spatial distribution of socioeconomic interactions according to ρ 3/2 (Eq. (3)). c Colour map of the scatter plot for correlation between nighttime light and AP 1.5 power. Brighter areas indicate that more data points fall in that small region and the colour bar indicates the number of it. The data are all normalised by the respective maximal value in a, b. Each pixel in a, b corresponds to a square with an edge length of 1 km
