【摘要】：正空间分析是地理信息系统(GIS)的核心功能,也是GIS深化应用与服务的重要支撑。现有空间数据分析方法在多维对象的自适应表达、空间数据的统一分析以及多维统一分析框架的构建方面仍显不足,无法满足海量、高维度、多要素的密集型GIS空间数据的分析需求。引入几何代数的多维表达结构及统一运算结构,从底层理论上对现有表达与计算方法进行创新,设计面向多维度、多要素复杂数据的计算模型,是突破传统GIS分析方法
[Abstract]:Positive spatial analysis is the core function of (GIS), and it is also an important support for deepening the application and service of GIS. The existing spatial data analysis methods are still insufficient in the adaptive expression of multi-dimensional objects, unified analysis of spatial data and the construction of multi-dimensional unified analysis framework. Multiple elements of intensive GIS spatial data analysis requirements. This paper introduces the multidimensional representation structure and unified operation structure of geometric algebra, innovates the existing representation and calculation methods from the bottom theory, and designs a multi-dimensional and multi-element complex data model, which breaks through the traditional GIS analysis method.
