空间数据存储研究及其在岩石圈深部探测数据中的应用

深部地球物理探测数据是岩石圈结构研究的重要资料,然而由于地学数据本身的多来源、多学科、海量等特点阻碍了数据的共享,而GIS技术恰好以强大的多学科交叉和空间数据处理功能为数据发布提供了新的途径。在GIS中信息的显示和分析方法都取决于地理信息数据模型,因此在利用GIS技术建立数据共享平台时,建立一个符合数据体查询和分析要求的数据模型尤为重要。笔者对几种空间数据存储方式和主流的空间数据模型进行了深入研究,最终结合深部地球物理探测数据的特点,以Geodatabase为基础建立了一个数据模型,为数据发布奠定了基础。

Spatial data storage and its application in deep geophysical survey data

Deep geophysical survey data are important information on the study of the lithospheric structure. However, data sharing was hindered by the characters of geoscience data such as multi-source, multidisciplinary and massive data. GIS can afford a new approach to data release because of its function of multiple discipline crossing and spatial data processing. The presentation and analytic methods of information in GIS depend on the data model; therefore it is important to construct a data model according with the need on data query and data analysis when the sharing platform was designed using the GIS technique. Several spatial data storage methods and main spatial data models are studied intensively. Finally, a data model is constructed for data release based on Geodatabase according to the characteristics of the deep geophysical survey data.
