Qu'est-ce (qui) est R tree - définition
TREE DATA STRUCTURE IN COMPUTER SCIENCE
R plus tree; R+-Tree; R+ Tree; R+-tree
R+ tree
An R+ tree is a method for looking up data using a location, often (x, y) coordinates, and often for locations on the surface of the earth. Searching on one number is a solved problem; searching on two or more, and asking for locations that are nearby in both x and y directions, requires craftier algorithms.
Priority R-tree
Priority R-Tree
The Priority R-tree is a worst-case asymptotically optimal alternative to the spatial tree R-tree. It was first proposed by Arge, De Berg, Haverkort and Yi, K.

R+ tree
An R+ tree is a method for looking up data using a location, often (x, y) coordinates, and often for locations on the surface of the earth. Searching on one number is a solved problem; searching on two or more, and asking for locations that are nearby in both x and y directions, requires craftier algorithms.
Fundamentally, an R+ tree is a tree data structure, a variant of the R tree, used for indexing spatial information.
