R-Tree spatial index for Python GIS

Project description

Rtree: Spatial indexing for Python

Build PyPI version

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
