Hilbert r tree
Webthe R*-tree is the concept of forced re-insert. When a node overflows, some of its children are carefully the sen; they are deleted and re-inserted, usually resulting in a R-tree with … 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
