Study on geographic disaster information monitoring in sensitive areas based on spatial analysis

In order to overcome the problems of low monitoring accuracy and efficiency in the current risk information monitoring methods, this paper proposes a spatial analysis based monitoring method for geographical risk information in sensitive areas. Firstly, this method constructs a real-time monitoring platform with monitoring terminal, information data collection, real-time monitoring and analysis, and designs and analyses the functional modules. Using spatial analysis technology and target location, the real-time collection of hazard information data and target centroid location are carried out. C/S model is used to manage the geohazard information data in sensitive areas. The concept of E-R chart is used to build a database, which provides data support for the monitoring process. The experimental results show that the accuracy and efficiency of the proposed method are high, and the highest monitoring accuracy is 98.7%.
