城市地质数据库结构设计与质量控制方法探究

Discussion of Structure Design and Quality Control Method of Urban Geological Database

城市地质数据具有多样性、不确定性和复杂性,为实现多源、异构、海量数据的有效管理与高效访问,本文全面分析了城市地质数据的构成及特点,结合国内城市地质调查数据现状和应用需求,参考《城市地质调查数据内容与数据库结构》等相关规范,开展了城市地质数据建库内容与结构设计,建立了“纵向层次、横向专业”的数据库结构,并针对性地探讨了数据建库过程中的质量控制措施,确保城市地质数据建库质量,为探讨本轮城市地质调查数据资源建设提供了建议指导。

Urban geological data has features of diversity,uncertainty and complexity.In order to realize the effective management and efficient access of multi-source,heterogeneous and massive data,the composition and characteristics of urban geological data are comprehensively analyzed in this paper.Combined with the current situation and application requirements of domestic urban geological survey data,and referring to relevant specifications such as Data and Database Structure of Urban Geological Survey,the content and structure design of urban geological data database construction are carried out,the database structure of"vertical level and horizontal specialty"is established.And the quality control measures in the process of data database construction are discussed to ensure the quality of urban geological data database construction,which provides suggestions and guidance for the construction of data resources of this round of urban geological survey.
