英文摘要	In component-based WebGIS system, map visualization objects are cornerstones in developing WebGIS applications. From constructing user interfaces, displaying maps and human-computer interactions to displaying query results and making subject maps, almost all developing work is based on map visualization objects. In this paper, a component-based WebGIS system Geo-Union is introduced, which is built by COM/DCOM technology and can run in Internet/WWW environment. After briefly describing the architecture and the functional partition of Geo-Union, the design and implementation of map visualization objects, including map visualization control (GxMapView), map object(GxMap), display layer object (GxMapLayer) and dynamic layer object (GxTrackingLayer), are described and discussed in details.; Computer Science, Information Systems; Engineering, Electrical & Electronic; CPCI-S(ISTP); 0
