Forest Ownership Management Information System Based On WebGIS

In recent years WebGIS appears to be a new development of GIS. With distributed WebGIS, an information system of forest ownership is established, which provides distance inquiry with operations like scaling, rambling on electronic maps over the Internet. Thus, users obtain simultaneously both spatial and business information. The system is also benefit to forest resource information management as a convenient operational platform.Aiming to web publication of the information, the paper first works over the visualization of spatial data and attribute data of the forest ownership management, then build an experimental system which provides distance inquiry in a direct and transparent way. The research work is summarized as follows.1 . After a thorough study on the present work about domestic forest ownership management and the application of WebGIS in forestry domain, a distance inquiry model is proposed to found an experimental system for management, which deals with both spatial and business information.2 . In response to the reform of forest ownership, a frame of mortagage loan on the forest ownership is founded with improved the efficiency of information retrieve, the functions of which include forest mortagate loan application, registry, log-on, account book management and statistics and so forth, which provides the user with accurate, fast information retrieve.3 . Since the data of the forest ownership is excessively large, a set of server clusters is normally needed, which causes the consideration of load-balancing of server clusters. So the paper proposes a load-balancing mechanism with a content-aware distributed algorithm, thus improves the efficiency of the operation.
