The Study And Application Of Distributed GIS Based On DCOM

The study in Distributed GIS is currently the hotspot and former in GeographicInformation Systems field. In this paper, it first introduces the concept and characteristicof distributed component object model technology (DCOM) and distributed GIS.Secondly, it analyzes the developmental trend of management of electric powercommunication resource. The paper also introduces how to construct the applicationsystem applying in modern management of electric communication resource based onthe technology of DCOM, thus it can satisfy the electric power corporation demand ofthe production and management.The paper regards distributed GIS in management of electric power communicationresource based on DCOM as the example, and explains from the system structure,function structure, database design and management and the technology realizing thesystem mainly.
