WebRTree. R-trees were first proposed by Guttman [Gut84] to index geographic data (points, lines, and polygons), in order to efficiently find data that satisfy geographic predicates (i.e., key {contains,contained-in,overlaps,equals} constant).The keys in a (2D) R-tree are "bounding boxes", i.e. rectangles which are aligned with the x and y axes. WebApr 7, 2014 · I am using the Rtree implementation of boost::geometry to store (lots of) 2D points. Now I need to do distance-based nearest neigbors queries.
