Multi-representation geographic information system based on object deputy model
一个基于对象代理模型的多表现地理信息系统

A new approach to realize multi-representation GIS(Geographic Information System) based on object deputy model was proposed.It allows geographic object to have multiple deputy objects which can be defined as its multiple representations since deputy objects can be used to represent object views and role multiplicity. Through object update propagation,this approach can support dynamic classification and maintain system consistency.In addition,bilateral links between objects and their deputy objects facilitate cross-representation query.A multi-representation GIS based on object deputy model had been implemented.The experiment shows our approach is more efficient than the traditional one.
