ABSTRACT
Conventional GIS are usually quite static, as they do not cover dynamic aspects of geo-objects in their data model. The information on the modeled domain is usually separated into models of geometric space (2D/3D) and thematic aspects (attributes). But if someone wants to develop a system that is capable of modeling objects of the environment including their history, presence, and future, most available systems lack expressive power. It has been demanded that a temporal GIS (TGIS) needs to provide functionality for spatiotemporal data storage, data handling, and analysis as well as visualization. These functions are usually more complex than in conventional GIS and are still an area of active research.
