Design And Implementation Of Waterways Integrated Information Management System Based On GIS

The paper relies on the project of integrated information system of the Suzhou Waterways for Manage Bureau, which is responsible for the construction, maintenance, administration and toll collection of waterways in entire metropolitan Suzhou area.The author's aim is to establish an integrated information system based on Geographic Information System (GIS). Thus the administration capability and efficiency can be enhanced.The following are designed and implemented based on Arc/Info, a GIS development platform.1. By analyzing the goal and task of the system, a C/S and B/S mixed frame, which includes Web Server, GIS Server, Database Server and browser, is developed. The function of the project contains data transmission, OA document delivery, data reporting of inner net, data performance of outer net and the access control of the system database.2. Since multiple information system set up by the departments of the bureau uses diversified database format, such as Oracle, Ms SQL, dbf, Excel and text file, etc, a data transformation platform which transforms data from different database to Oracle database quickly and efficiently, is designed. Furthermore, the database can be converted in batch format by using XML.3. A GIS platform of waterway information management is implemented. This platform supports the creating of the waterway electronic map, displaying of space data, querying, inputting and outputting so that the points (such as locations for observation, toll collection, navigation, bridge, and harbor, etc), lines (such as waterways) and slides (such as districts) of the system can easily be shown as well as some related information.4. Some space analyzing methods like cascade analyzing, buffer-area analyzing and network analyzing on the waterways electronic map are illustrated. The best routing are implemented by using the Dijkstra arithmetic within the example of searching the shortest route between the stages.Therefore, the system can be seen as a powerful tool for the quickly control of the whole situation and efficiently management of the entire area by the Bureau.
