WebHilbert R-tree - Dynamic Hilbert R-trees - Insertion Insertion To insert a new rectangle r in the Hilbert R-tree, the Hilbert value h of the center of the new rectangle is used as a key. At each level the node with the minimum LHV value greater than h of all its siblings is chosen. WebHilbert Packed R-Tree written in JavaScript. This is an implementation of a Hilbert Packed R-Tree. R-Trees are a special data structure for indexing spatial data. To improve the performance of query operations on the data structure, the R-Tree has been packed using the space filling Hilbert Curve.
