大数据的空间数据索引技术研究

The Research of Spatial Data Indexing on Large Scale Data

详细了解大数据的空间数据索引技术研究现状，对目前的一系列主要空间数据索引进行阐述。对现在的主流空间数据索引技术进行论述，依据R-tree索引、哈希索引、Voronoi图索引和空间填充曲线的原理，从其本质上分析其各自特点，从而为大数据的空间数据索引技术研究提供理论基础。

In this paper, the status quo of spatial date index research on large scale data is studied, and a series of major spatial data index at present are expounded. Based on the principle of the R-tree index, Hash index, Voronoi map index and Space filling curve, this paper discusses upon the mainstream of the spatial data index technology fully ar, d analyzes their characteristics in nature so as to provide the foundation theoretical basis for the spatial daie index research on large scale data.
