Abstract:Based on ArcGIS Server with powerful spatial visualization and analysis tools of geographic information system(GIS),as well as the SQL Server database,a network monitoring system that can be used in landslide hazards is introduced. In this system,based on studying the spatial and attribute data modeling and online visual query,the professional module which includes multi-view analysis methods:profile analysis,planar analysis and 3D (three-dimensional) analysis,is provided. Using this module,the functions of graphical expression,interpolation and trend analysis of monitoring information in section,plane and 3D view are achieved respectively. In all,the developed system implemented the needs of functions:the integration of spatial and attributes data,visual display and online inquiry,powerful spatial analysis,etc.;and it is extensively applicable. So it would play an important role in Web-based real-time monitoring data analysis and assessing safety condition of landslides as well as forecasting decision making.
