空间数据立方体多维信息空间分析实例*

多维信息空间分析是构筑数字城市最为关键的技术之一,而空间数据立方体是解决这个关键技术问题的有效途径;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,简单介绍了这些分析操作功能和结构;在分析操作过程中,采用具体分析功能和例子数据相结合的直观方式列举了多维信息的缓冲区分析、连接分析、网络分析实例.

Example of Multi dimension Spatial Analyses on Spatial Data Cube

This paper thinks that multi-dimension spatial analyses is one of key technology to build digital city,it is good method to slave this key technology for spatial data cube.This paper states basic concept and principle of analytical operation of spatial data cube,and also discusses that the analysis operation of spatial data cube makes up of recapitulative analysis,local analysis,global analysis and pivoting analysis.According to these,this paper recites completely function and structure of these analysis and details process of analytical operation for multi-dimension analyses.In the process of analysis,examples are showed such as buffer analysis,network analysis,connection analysis,the methods that show example for these analysis functions are adopted in order to make reader more intelligible.
