Abstract

The need to represent and manage the temporal aspects of the geographic reality has demanded efforts in the geoprocessing area. The complexity of the spatio-temporal information manipulated by a Geographic Information System (GIS) has demanded special efforts for the creation of a conceptual data model able to represent reality phenomena naturally. This paper presents some requirements of a temporal conceptual model for GIS applications. Then, the conceptual framework GeoFrame-T is presented as a temporal extension of the conceptual framework GeoFrame, which was proposed by Lisboa [1]. GeoFrame is based on the OO formalism and uses the Unified Modeling Language - UML as modeling language. The temporal extension proposed for GeoFrame expands some concepts of Temporal Unified Modeling Language - TUML [3], adapting it to the spatio-temporal view, making it possible to model geographic phenomena in a more realistic way.
