空间数据工程理论框架研究

Geo-spatial Data Engineering: A Theoretical Framework

随着地理信息系统应用的深入发展,如何更加高效地组织和利用地理空间数据成为空间信息科学研究的一项重要内容。为了从工程实施的角度来更好地创建、管理和使用空间数据,笔者提出了空间数据工程的概念。该文对空间数据工程以及相关概念进行了定义,同时描述了空间数据工程元模型和相关的两个子元模型,从而建立了其理论框架。最后,描述了空间数据工程所要解决的问题以及其研究内容。

With the progress of GIS applications, how to organize and make use of spatial data efficiently is becoming an important content in the research of spatial information science. In order to use spatial data in the view of engineering, the author brings forward the conception of geo-spatial data engineering (GDE). Based on the definition of GDE and the relative conceptions, this paper describes geo-spatial data engineering meta-model and two correlative sub-meta-model, which compose the theoretical framework of GDE. In the end, the author presents researching content on Geo-spatial data engineering.
