Places, Networks and Flows

Geographers conceive of networks and flows between places as a foundational spatial concept. Geographic information systems (GIS) are the main analytical tools employed in determining relations between individuals, settlements, modes of transport, and infrastructures like power grids, and communication networks. The concepts can also be applied to food flows, traffic network analyses, accessibility and mobility studies, spatio-social networks, disease spread, migration, healthcare service delivery, crime activities, river networks and atmospheric teleconnections.
