摘要

提出了一种针对固定网络中移动对象的时空索引2DSTIH及其相应的时空查询算法.2DSTIH采用降低时空数据维度的思想

使用Hilbert曲线将移动对象的3维运动空间(x

t)转换为2维的运动空间(x

将一个3维的时空索引转换为两个2维的子索引.这种2维时空索引机制降低了索引的数据维度

支持当前轨迹和历史轨迹的时空查询操作

并且有效的优化了窗口查询操作.

Abstract

A new spatiotemporal index for moving objects on fixed network

named two-dimensional spatiotemporal index for moving objects in network by using Hilbert(2DSTIH)

and a set of spatiotemporal query algorithms are proposed in this paper.2DSTIH based on the idea of dimensionality reduction

converting the three-dimensional(x

t) space to the two-dimensional(x

t) space by Hilbert curve

the single 3D index are replaced by two 2D sub index.The 2DSTIH reduces the dimension of spatiotemporal index

supports the effici...
