Simple non-academic performance comparison of available open source implementations of R-tree spatial index using linear, *quadratic and R-star balancing algorithms as well as bulk loading (Sort-Tile-Recurse or combined methods).
List of currently measured libraries:
More libraries have been suggested, see the GitHub Issues.
- C++11 compiler
- Boost headers current SVN trunk which includes required internal utilities:
- libspatialindex headers and libraries (for Windows, use OSGeo4W.
First prototype, API usage and parameters matched as much as I could, hopefully without major bugs.

query 100000 - number of instersection-based queries with random boxes 10x larger than those inserted
stats generated using lsi's API and purposely written visitor for Boost.Geometry (not yet in Boost trunk)
This project is driven by curiosity and for my own purposes, with hope to obtain useful and interesting results, for myself and others too. I do not have any objective of making ultimate performance shootout. This is not a rocket science, but a simple set of C++ programs, with likelyhood of bugs or inconsistencies. Found any, please report. Comments and improvements are always welcome!
