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,y,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...
