WebIt uses the Hilbert Curve to order the keys in an RTree, which places close points relatively close in the tree. This makes it efficient to find other near points or intersecting points because much of the time all the geometric features inside a bounding box are all on the same branch of the tree. Building Hilbert R-tree, an R-tree variant, is an index for multidimensional objects such as lines, regions, 3-D objects, or high-dimensional feature-based parametric objects. It can be thought of as an extension to B+-tree for multidimensional objects. The performance of R-trees depends on the quality of the algorithm … See more Although the following example is for a static environment, it explains the intuitive principles for good R-tree design. These principles are valid for both static and dynamic databases. Roussopoulos and … See more The following provides a brief introduction to the Hilbert curve. The basic Hilbert curve on a 2x2 grid, denoted by H1 is shown in Figure 2. To derive a … See more The performance of R-trees depends on the quality of the algorithm that clusters the data rectangles on a node. Hilbert R-trees use space-filling curves, and specifically the Hilbert curve, to impose a linear ordering on the data rectangles. The Hilbert value of a … See more

It can be thought of as an extension to B+-tree for multidimensional objects. WebThe Hilbert R-tree index algorithm based on the nodes clustering is proposed, which resolves preferably the clustering storage for the adjacent data, decreasing the leaf nodes MBR area and the spatial overlap between interior nodes. 【Abstract】Considering that R-tree is suitable for the dynamic index, its spatial overlap between nodes is great, and …
WebJul 3, 2024 · In this paper, a new Hilbert R-tree indexing method is proposed based on CLUBS+ clustering and Hilbert filling curve. Compared with Hilbert R-tree, this algorithm takes less time to generate R-tree, has high space utilization, covers less and overlaps less area, and improves the performance of indexing to a larger extent. 2 Related Work
