三维R树在空间数据索引中的应用

Application of 3D R-tree in the Spatial Data Index

随着GIS在军事和民事上的应用,国内外学者已经研究出各种各样的空间数据索引以提升系统性能。在总结目前空间数据索引技术研究进展的情况下,重点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树索引技术。

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. Mainly presents an efficient 3-demensional R-tree based on spatial cluster grouping for 3-demensional spatial database after summarizing the researches on the spatial data index techniques up to the present.
