摘 要:地质灾害基础数据具有多源性、异构性、多尺度等特点,大量的数据没有形成统一的管理模式,共享程度较低。当前普遍施行的地质灾害数据管理,采用的是从多角度、多层面、多空间等对地质灾害体及其孕育环境表达的多尺度数据集,因此各类数据的表达形式、数据精度、数据质量、时间表达等多方面存在着较大的差异性。构建了地质灾害多源异构数据集成方法体系,系统总结了数据的结构特征与管理方法,结合数据结构特征,使用PostgreSQL数据库管理属性数据,使用MongoDB数据库集群进行管理,使用GeoServer平台进行空间数据服务发布。研发地质灾害大数据ETL工具,集成数据库驱动、数据库适配器、数据模型等模块,实现对多源异构地质灾害大数据的有效管理。研发了一体化数据管理可视化平台,实现对各类数据进行统一管理与集成,为地质灾害基础数据的统一管理提供了综合数据平台,为地质灾害的防灾减灾、应急决策等提供数据和平台支撑。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.
