Abstract: On the basis of data models that are applied in the fields of CAD, virtual reality and simulations, a new featurebased objectoriented data model for virtual GIS is initiated, in which featurebased modeling techniques and objectoriented approaches are applied. With Oracle ORDB management model an objectoriented virtual GIS database framework is thus established. Making use of the new data model, a Client/Server structured virtual GIS prototype system is implemented.

Key words: featurebased, virtual GIS, objectoriented, data model
