Hilbert r tree

WebJan 1, 2024 · The Hilbert R-tree (Kamel and Faloutsos 1994) is a hybrid structure. It is a B + -tree with geometrical objects being characterized by the Hilbert value of their centroid. The structure is based on the Hilbert space-filling curve which has been shown to preserve the proximity of spatial objects very well. WebR-Trees are a special data structure for indexing spatial data. To improve the performance of query operations on the data structure, the R-Tree may be packed using the space …
