NDLI: GeoFrame-T: a temporal conceptual framework for data modeling

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.
