地质图空间数据库自动检查系统的设计

地质图空间数据库数据量大, 内容复杂, 为了保证数据库的质量, 在地质图空间数据库的建立过程中, 对数据的全面系统检查工作是非常必要的。对于地质图空间数据库, 检查属性数据库的内容以及属性数据与空间图形数据的正确链接是难点之一, 也是一项最耗时的工作。为了科学、快速地检查地质图属性数据, 保证属性内容的正确性以及非空间数据与空间数据的正确对应, 针对这一问题, 在进行全国1:100万地质图空间数据库的检查时, 设计开发了属性数据库的自动检查系统。本文以近期完成的全国1:100万地质图空间数据库的检查系统设计研究为例, 主要介绍了地质图数据库属性数据自动检查系统的设计开发, 其中详细介绍了各模块可以实现的主要功能。通过此项检查, 能够提高入库数据的质量, 为数据库后期的应用与共享提供可靠保障, 从而为地质科学研究、矿产勘查及生态环境治理等提供科学的地质图数据资料。

The Design of the Automatic Checking System for Geological Map Spatial Database

The geological map spatial database is large and complicated. To ensure the quality of the database, it is essential to check the data systematically during the database construction. In design of the geological map spatial database, the check of the content of the attribute database and the proper connection between the attribute data and the spatial map data constitute one of the difficult points and also the most time-consuming work. In order to ensure the correctness of the attribute data and the correct correspondence between space and non-space data, and to check the geological map attribute data quickly, the authors have designed the automatic checking system for attribute database of the national geological map (1:1M). With the recent spatial database of the national geologi-cal map (1:1M) as an example, this paper presents the design of automatic checking system for geological map spatial database and describes the function of the modules in detail. This checking system improves the data qual-ity, provides a reliable guarantee for data application and sharing, and also supplies scientific geological map data to geoscience research, mineral exploration and ecological environment renovation.
