‘Everything is related to everything else, but near things are more related than distant things.’ Tobler’s first law of geography has established the theoretical foundation of spatial interaction in the analysis of associations between geographic entities. Modeling accessibility, mobility, and connectivity of service facilities, objects, agents, and individuals, as a proxy for the spatial interaction between entities and among people, has been widely explored in GIScience and topical areas such as transport geography, health geography, and land use-land cover analysis. These explorations primarily serve three purposes: (1) a diagnostic purpose identifying the spatiotemporal patterns of human dynamics as well as the relations and connections between human and their living environment, (2) a planning purpose evaluating if land use or transport systems can effectively cater to the need of residents or commuters, and (3) a corroborative purpose identifying if social inequality exists among different identity groups.

In this session, we seek innovative methods and applications that advance our traditional understanding of accessibility, mobility, and connectivity in urban, rural, as well as virtual contexts. The session highlights the development of cutting-edge geospatial modeling techniques and their case studies by critically applying accessibility, mobility, and connectivity theories.
