Time Geography Rediscovered: A Common Language for Location-Oriented Services

We propose that the concepts of Time Geography be evaluated as a framework for use within location-oriented services. Originally conceived as a system to describe patterns in human migration, Time Geography is ideally suited for providing the common lan-guage and concepts necessary for dialogue within this evolving area. Location-oriented services have been the focus of a great deal of attention, but with research occurring in many disparate disciplines, the lack of a common model that can conceptualize these ideas has not received appropriate attention. To demonstrate its applicability within location-oriented services, we present a research activity which makes explicit use of concepts from Time Geography, with the hope that it can be seen as a tractable and practical solution for several difficulties facing this fast growing area of interest
