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. 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
