Journal ArticleDOI
Indexing the positions of continuously moving objects
TL;DR: A novel, R*-tree based indexing technique that supports the efficient querying of the current and projected future positions of moving objects and is capable of indexing objects moving in one-, two-, and three-dimensional space is proposed.
Proceedings ArticleDOI
STR: a simple and efficient algorithm for R-tree packing
TL;DR: The results from an extensive comparison study of three R-tree packing algorithms are presented: the Hilbert and nearest-X packing algorithms, and an algorithm which is very simple to implement, called the STR (Sort-Tile-Recursive) algorithm.
Proceedings ArticleDOI
A greedy algorithm for bulk loading R-trees
TL;DR: CM-line loading of R-trees is useful to improve node utilization and query performance and is the method of choice for data with skew in locations, areas, or aspect ratios.
Proceedings ArticleDOI
High dimensional similarity search with space filling curves
TL;DR: The solution is dynamic, allowing insertion or deletion of points in O(d log/sub p/ n) page accesses and generalizes easily to find approximate k-nearest neighbors.
Journal ArticleDOI
Generalized intersection searching problems
Ravi Janardan,Mario A. Lopez +1 more
TL;DR: Algorithms with efficient, output-size-sensitive query times are presented for the generalized versions of a number of intersection searching problems, including: interval intersection searching, orthogonal segment intersection searched, Orthogonal range searching, point enclosure searching, rectangle intersection searching and segment intersection searching.
