Rtree is a ctypes Python wrapper of libspatialindex that provides a number of advanced spatial indexing features for the spatially curious Python user. These features include:

• Nearest neighbor search
• Intersection search
• Multi-dimensional indexes
• Clustered indexes (store Python pickles directly with index entries)
• Bulk loading
• Deletion
• Disk serialization
• Custom storage implementation (to implement spatial indexing in ZODB, for example)

Wheels are available for most major platforms, and rtree with bundled libspatialindex can be installed via pip:

pip install rtree
