Application Web GIS To FM

Jihua HuDirected by Jianjun TanFacilities management (FM) is an important part of computerized government affairs, but there are many problems exits in present FM, such as the difficulty to maintain the integrity and greenness of data, the handicap exits in data exchanging and data sharing, the shortness to provide evidence for decision-making, and so on.There are many reasons: no standard in data exchanging and data sharing, no integration of workflow technology and real time data collecting technology, and no plan when constructing system. To solve them, it is essential to fully understand the contents and laws of the management of urban facilities, to update current systems through Web GIS, to choose a standard for data exchanging and data sharing, to integrate related technologies through COM method.The life cycle of urban facilities includes planning, designing, construction, fixing, working, maintaining and other phase. Enlightened by this we provide detail information of the management of telecom, water supply, electricity supply, etc. and there comes a conclusion that the urban facilities is actually a dynamic network system with multi-layers.many technologies that will be used when urban facilities are managed through Web GIS are analyzed. They are Object-Oriented theory, workflow technology, GPS and the technology managing spatial data through relation database. XML is chose as the standard of data exchanging and the core of the implement of Web GIS.Directed by Object-Oriented theory and software engineering, a technical flow of development is provided for managing urban facilities through Web GIS, which includes preparing, analyzing, designing, test and other phase. At last, illustrated by the development of GuangZhou Telecom facility management, the details of analyzing and design is described, which is the core phase to construct FM, this phase revived the contents and laws of the management of telecom facilities. The later result improves that it is possible and proper to manage urban facilities through Web GIS, and those problems before are fixed.
