Dynamic Management and Application of Spatial Data for Dam Group Safety Monitoring Based on GIS

There are some matters about dam group safety monitoring spatial information, such as large amount of data, complex structure, difficult to maintain when it changes. To solve these problems, GIS technology is used for dynamic management and application of spatial data. We propose a dynamic management technology flow and a batch information interaction method are formed by classifying and storing the spatial data of dam safety monitoring, and develop the spatial data application service module. It can realize the dynamic management, batch processing and visual application of massive heterogeneous spatial information of dam group safety monitoring, further improve the efficiency of spatial data management, and enhance the maintainability of dam safety automatic monitoring system.
