To propose geolocated mobile phone data as a global standard for dynamically defining and delineating urban areas based on human presence and mobility flows.
Assessed global geolocated mobile data from over 7 billion cell-phone users as an empirical proxy for temporal and spatial human connectivity.
Framed computational modeling methods to synthesize movement patterns and population concentration with statistical and administrative boundary requirements.
Geolocated cell-phone records effectively capture both stationary population density and cross-area movement flows at expansive geographic scales.
Dynamic data-driven delineations adapt to varied administrative and scientific research needs more effectively than static, traditional definitions.
