Concepts

  • [CF4b] Fundamentals of Geographic Information
    Geographic phenomena, geographic information, and geographic tasks are described in terms of space, time, and properties. Different theories exist as to the nature and formal representation of these aspects, including space-like dimensions, sets, and phenomenology. Information in each of these three aspects is measured and reported with respect to one of several frames of reference or domains, including both absolute and relative approaches. Early frameworks such as those of Berry (1964) and Sinton (1978) were influential in setting forth the importance of space, time, and theme in GIS&T. Besides, space, time, and properties, categories are also fundamental in the conceptualization and representation of spatial entities, phenomena, processes, and events. Distinctive features of geographic information such as scale and detail, spatial patterns, spatial integration, and regions are also critical for a complete description of its nature and representation. This unit is closely tied to the creation of data models in Knowledge Area 5: Data Modeling, Storage, and Exploitation.
