The integration of multi interactive patterns in Virtual Geographic Environment
Virtual Geographic Environment will be a modeling system supporting geographic analysis and visualization for geographic research on modern distributed,heterogeneous network environments.It allows users at different geographic locations sharing spatial information and interacting with each other via Internet.This paper proposes a new multi pattern interactive architecture for presenting different application patterns.The architecture for the integration of multi interactive patterns is separated into three main function layers:Data Layer,Virtual Geographic Environment Layer,and Application Layer.With the multi pattern interactive architecture,the Virtual Geographic Environment behaves itself with multiple application features,each of which is managed by a uniform object which is named Entity.The objectoriented conceptual modeling mechanism is presented by Entity and the relationship between them.In order to fulfil the various interactive patterns of the Virtual Geographic Environment according to the users requirements,multiple application aspects are integrated dynamically,such as Geo-spatial data sharing,Geographic model integration,twodimensional map,three-dimensional simulation and so on.
