摘要：Today with the fast advancement of spatial data acquisition ability, the update circle of data becomes shorter and shorter and the volume of spatial data increases more and more, and distributed storage and extraction becomes the primary management means of spatial data. The geographic information is collected and managed by a multitude of private and public agencies. Distributed infrastructure in urban geographic information public platform(UGIPP) has traditionally tackled the problems associated with the inter-connection of a number of computer systems in urban departments and companies. Thus we have to be up against the access difficulty of heterogeneous distributed spatial data and collaboration spatial data process. Efficiency of database connection and collaborate spatial data process becomes one of the main factors that affect WebService, and how to optimize it is very important. This paper summarizes the results of research and development towards internet-based support of collaborative spatial data process, and discussed key issues in applying CSCW technologies in distributed spatial data environment. The results indicate that connecting pool, collaborative spatial date process, groupware principles can be effectively brought together and applied to provide better solutions to implement distributed heterogeneous spatial data share and service
