系统地介绍了面向数字城市多源数据的空间数据立方体分析操作的基本原理,提出了空间数据立方体的分析操作主要由概括分析、局部分析、全局分析和旋转分析组成。在此基础上,全面叙述了空间数据立方体概括分析、局部分析、全局分析和旋转分析的功能和结构以及分析操作的详细过程。
This paper stated basic concept and principle of analytical operation of spatial data cube on object-oriented multisource data for digitial city, and also discussed that the analysis operation of spatial data cube made up of recapitulative analysis, local analysis, global analysis and pivoting analysis. According to these, this paper recited completely function and structure of these analysis and detailed process of analytical operation of spatial data cube. The methods show that examples for these analysis functions are adopted in order to make reader more intelligible.
