Research on management system of geological hazard data supported by big data technology
In order to efficiently organize,store and apply massive,multi-source and heterogeneous geo-logical hazard data,this paper analyzes the current requirements of the data management,studies such key technologies as distributed data collection,differentiated data storage management,data cleaning and fusion,and data visualization expression.And it designs and develops a geological hazard data management system using big data technology.This system can realize the geological hazard data col-lection,storage,cleaning,fusion,and visual analyzing,greatly improve the utilization efficiency and value of geological hazard data,and it can provide detailed and accurate data support for geological haz-ard preventing and responsing.
