Temporal Geographic Information System (GIS) is an emerging capability in GIS for integrating temporal data with location and attribute data. Temporal data specifically refers to times or dates, enabling temporal visualization and ultimately temporal analysis. Temporal data may refer to discrete events, such as lightning strikes; moving objects, such as trains; or repeated observations, such as counts from traffic sensors. Temporal changes occur at different points or periods of time and are recognized by changes in spatial properties and/or locations. A temporal GIS processes, manages, and analyzes spatio-temporal data;  spatial data that changes with time and is part of the geographic movement. The study of modeling temporal information in GIS started in the mid-1980s. The field of computer science's development of temporal data models influenced temporal modeling in the GIS field. Temporal modeling in computer sciences began with the integration of time with relational databases and later extended into object oriented modeling. ... more
