System to integrate and manage multi-source data on geological hazards and its application
The basic data on geological disasters have multiple sources;they are heterogeneous and collected at varying scales.No unified system is currently available for managing the large amount of data on such disasters.Such data constitute a multi-scale dataset that represents the relevant area as well as the environment from multiple angles,layers,and spaces,and this leads to significant differences in their forms of expression,accuracy,quality and tempral representation.In this paper,we construct a system to integrate the multi-source and heterogeneous data on geological disasters,and systematically summarize their structural features and methods to manage them.We used the PostgreSQL database in conjunction with the structural features of data to manage their attributes,and applied the MongoDB database cluster to manage them.The GeoServer platform was used to share the spatial data on geological hazards.Moreover,we used the ETL tool used to handle big data on geological disasters,and integrated a database driver,database adapter,data model,and other modules into the system to effectively manage the multi-source and heterogeneous data.We then developed an integrated data management and visualization platform to handle the different kinds of data.It is a comprehensive platform for the unified management of basic data on geological disaster,and provides data and platform-related support for the prevention of geological disasters and rapid decision-making in their aftermath.
