Spatial interaction in human geography examines the interdependence between entities located in different places. Proximity, distance, and barriers influence the intensity of this interaction, which is affected by factors like connectivity, time-space convergence, and interaction strength. Models such as gravity, friction of distance, and intervening opportunities help predict and analyze spatial interaction. This analysis finds applications in transportation planning, urban development, and marketing, providing insights for informed decision-making and improved outcomes by considering spatial relationships in human and economic systems.
