Management System Based On Gis Inland Waterways Development

Effective inland waterway management system was the important guarantee of traffic safety on waterway. Around the design and development of inland waterway management system based on GIS, the main study content was composed with the following parts:Present situation of waterway management at home and abroad was analyzed. And the application of GIS technology to waterway management was discussed.The system frame of inland waterway management was established with the basic function of rescue information query on waterway and navigation mark positioning. The system was divided into three sub-systems, as the sub-system of GIS, the sub-system of rescue information query and the sub-system of navigation mark positioning. The GIS components technology and the technical characteristics of MapX were studied deeply. The development mode of the system was integrated secondary development of MapX and Visual Basic. And the sub-systems were designed clearly.The key technologies involved in the development of the system were studied in detail. On the basis of information classification, the information about waterway and rescue materials was coded with the support of the encoding technology. The inland-waterway electronic map was produced with MapInfo and the support of vectorization technology. Based on Digital Elevation Model, the cruising video of three-dimension waterway was produced with IMAGIS. The storage structure of waterway categorical data was designed. Rescue information query of multi-directions and multirange was achieved by the utilization of database store technology and the powerful query function in GIS. The real-time monitoring of navigation mark was achieved by the application of navigation mark information transmission technology and GPS data extracting technology. And the system software was made on the basis of the detail design of system.The study of the thesis was good to improve the efficiency of waterway management. And a new research thinking of waterway management was provided.
