The analysis of big data continues to tell us more about ourselves. Location based data, which identifies the location of mobile users, is being used to examine various attributes about the population, including population densities, commuting patterns, growth patterns and mobility.
One of the outcomes of this research is to define the boundaries of existing cities, a classic problem of city planners. After all, the political boundaries are often almost arbitrarily determined, with the result of, for example, rural and urban dwellers having little in common being clustered together under one central urban government. The determination of the natural boundaries also helps city planners to evaluate the dynamics of proposed development schemes, by knowing where the city is likely to grow.
