“Spatial” refers to the location, arrangement, and distribution of things, including human activities, people, and resources, across the Earth’s surface and within physical environments, making it a fundamental concept in geography and other fields like sociology and urban planning. Human activities, from daily journeys to the migration of populations, inherently occur within a spatial context, influencing and being influenced by physical environments and leading to distinct spatial patterns and relationships that are studied to understand human behavior, resource use, and societal development. The Chapter reviews spatial as the basic feature of various human activities with references to related sources and publications, and expresses the need for a unified philosophical, psychological, and technological approach for investigation and problem management in these and other spatial areas.
