Feb 6, 2024 · Quadtrees are trees used to efficiently store data of points on a two-dimensional space. In this tree, each node has at most four children.
Jan 31, 2017 · I've heard that quadtrees (as used in spatial-indexing) can be implemented on top of the B-tree structure for non-spatial indexes.
A quadtree is a tree data structure in which each internal node has exactly four children. Quadtrees are the two-dimensional analog of octrees.
