Abstract
An ontology-based generalization scheme is presented with specific reference to object attribute data subjected to space and time constrained extraction and presentation. The method is expected to be of value in mobile GIS for providing travelers with additional spatial information while moving. The space constraint is given by the boundary of an object-specific area of information relevance. The time constraint is given by the number of time units available to present the information as a function of the speed of travel and the spatial distribution of objects. An algorithm for changing the duration of the attribute data presentation is presented. A geodata-ontology is used to specify meaningful tran sitions betweeen levels of generalization.
