Research on the synchronous display of Collaborative Geography Information System

In Synchronous Collaboration Geography Information System, it more important to achieve synchronous display of the graphics. Aiming at the characteristics of the map operation, the paper presents the operation between people and computer in Geography Information System(GIS) and researches on the synchronous visualizing of GIS map. Then, it poses a technique that synchronous collaboration basing on operation driving and makes further study on how use XML to describe GIS map operation. Finally, the paper achieves the packaging and parsing of GIS map operation.
