中国地下水资源空间数据库标准化研究

Standardization of Spatial Database for Groundwater Resources in China

结合新一轮全国地下水资源评价工作的实际情况,对评价工作涉及到的数据信息进行了综合分析,建立了数据的层次结构模型,进而提出了空间数据库图层的划分方案,结合MapGIS软件系统的数据格式给出了空间数据库的图层与属性的存储结构,并探讨了与空间数据库相关的数字制图等技术问题。

In combination with the actual conditions of a new round of nationwide groundwater resources assessment, a comprehensive analysis of the data information has been made and an administrative structure model of the data has been constructed. In addition, the division plan of spatial database map layers has been proposed. In combination with the data format of the MapGIS software system, the storage structure of spatial database map layer and the storage structure of the attribute have been explained, and the digital mapping related to the spatial database has been discussed.
