GIS空间数据结构的研究

Research of Spatial Data Structure in GIS

在对两种主要的空间数据结构的优、缺点进行总结的基础上,指出研究时空数据结构的必要性和紧迫性,在大量调研国内外有关文献的基础上,对时空数据的概念框架、时空数据结构的特征等问题进行了分析。

Based on the advantages and disadvantages of two kinds of main spatial data structures, we propose the necessity and imparity of spatial data structure research. By investigating a lot of relative references at home and abroad, we analyse the problems of concept framework of spatiotemporal data and features of the spatiotemporal data structure so as to provide references for the further research of the spatiotemporal data structure.
