【摘要】：空間關(guān)系表達(dá)了空間數(shù)據(jù)的相互約束,在空間查詢語(yǔ)言、數(shù)據(jù)檢索及空間分析中具有重要作用。當(dāng)前關(guān)于空間關(guān)系的研究,多基于簡(jiǎn)單地理對(duì)象,或者只對(duì)某一種空間關(guān)系進(jìn)行獨(dú)立的算法設(shè)計(jì),難以滿足多粒度對(duì)象多種空間關(guān)系的統(tǒng)一表達(dá)與計(jì)算。為此,本文利用幾何代數(shù)運(yùn)算的對(duì)象無(wú)關(guān)性和維度無(wú)關(guān)性,構(gòu)建簡(jiǎn)單對(duì)象空間關(guān)系計(jì)算算子,并將其推廣到多粒度對(duì)象,實(shí)現(xiàn)全空間地理信息系統(tǒng)框架下多粒度對(duì)象三種空間關(guān)系的一體化表達(dá)與計(jì)算。最后,以三角網(wǎng)求交算法為例,證明了算法的可行性,為全空間GIS中空間關(guān)系的表達(dá)和計(jì)算提供了借鑒。
[Abstract]:Spatial relations represent the mutual constraints of spatial data, and play an important role in spatial query language, data retrieval and spatial analysis. At present, the research of spatial relationship is based on simple geographical object, or only one kind of spatial relationship is designed independently, so it is difficult to satisfy the unified expression and calculation of multi-granularity object and multi-spatial relationship. In this paper, the object independence and dimensionality independence of geometric algebraic operations are used to construct a simple object spatial relation computing operator, which is extended to multi-granularity objects. The integrated representation and calculation of three spatial relationships of multi-granularity objects under the framework of full spatial GIS are realized. Finally, the feasibility of the algorithm is proved by taking the triangular intersection algorithm as an example, which provides a reference for the expression and calculation of spatial relations in the full-space GIS.
