R-trees are tree data structures used for spatial access methods, i.e., for indexing multi-dimensional information such as geographical coordinates, rectangles or polygons. The R-tree …

Sep 5, 2022 · Tiling level optimization is required in Quad-trees whereas an R-tree doesn't require any such optimization. Quad-tree can be implemented on top of existing B-tree whereas R …

The description that follows will focus on the R-Tree structure and how queries are handled, anyone interested in R-Trees handle insertions and deletions should consider the papers …

Although not required in this course, there are fast algorithms to perform deletions from an R-tree. The instructor will discuss this in the class if time permits.

The R-tree is intended for indexing two (and higher) dimensional objects in terms of their minimum bounding rectangles (MBR). Nodes of the tree store MBRs of objects or collections of objects.

Similar to the B-tree, the R-tree is also a balanced search tree (so all leaf nodes are at the same depth), organizes the data in pages, and is designed for storage on disk (as used in databases).
