海洋地质调查数据库系统的数据组织

DATA ORGANIZATION FOR MARINE GEOLOGICAL SURVEY DATABASE

采用地理信息系统平台建立数据库,可以利用要素类和数据表对数据进行管理,但是,地理信息系统软件平台提供的数据表、要素类等数据对象并不能满足多样性的海洋地质调查数据的存储和管理需求,还需要以各种格式的数据文件形式对数据进行存储和管理,通过数据表关键字段将各种数据关联起来,把各种数据组织成一个完整的数据库。根据数据管理、数据可视化、数据应用等需求,讨论了各种海洋地质调查数据在数据库系统的数据组织管理方案。

The database built upon the GIS platform can manage data in the forms of features or tables.However,the features and tables provided by the GIS platform are far from sufficient to the management of diverse data from marine geological survey.Files of various formats have to be used to store and manage data,and all kinds of data should be integrated by keywords to become a integral database system.To meet the requirement of data management,data application and data visual display,possible ways are discussed in this paper for organization and management of various data from marine geological survey.
