| The Design and Implementation of WebGIS Meteorological Forecasting and Warning Information System of Slope Geological Hazards Based on RIA: A Case Study of Nujiang |
| Frequent slope geological hazards often cause serious economic loss, but the slope geological hazards forecasting and warning can serve as the means for reducing the economic loss. This paper described the present situation of the study and development of the geological hazards forecasting and warning method and the WebGIS system, and designed a WebGIS framework by introduction of advanced RIA technology. For the system requirement analysis, the authors designed the overall system and specified many implementation details; for instance, a spatial database was built based on ArcSDE Geodatabase and SQL Server technology. Finally, a WebGIS weather forecasting and warning information system based on RIA technology for slope geological hazards was built on Visual Studio 2010 development platform with C# language. Many function modules such as query retrieval, statistical analysis, spatial analysis, and thematic map production, forecasting and warning, dynamic maintenance were incorporated in the system. The design and implementation of the system is aimed at improving the initiative, efficiency and accuracy of hazards prevention and mitigation of slope geological hazards and minimizing the casualties and property losses caused by rainfall-induced slope geological hazards. This system was tested and used with related data collected from Lisu Autonomous Prefecture of Nujiang in Yunnan Province, and the results provide strong technical support for slope geological hazards prevention and forecast in this area. |
