摘要
随着GIS在军事和民事上的应用,国内外学者已经研究出了各种各样的空间数据索引以提升系统性能。本文在总结目前空间数据索引技术研究进展的情况上,重点地介绍一种适用于三维空间数据库的基于空间聚类的三维R树索引。
with the military and civil application of GIS, domestic and overseas scholars have proposed all kinds of spatial data index techniques to improve the system performance. In theis paper, the present research of spatial data index technology is summarized firstly.This paper mainly presents an efficient 3-demensional R-tree based on spatial cluster grouping for 3-demensional spatial database.
