GeoPandas 1.0 and beyond — Martin Fleischmann

GeoPandas provides subclasses of Pandas objects - GeoPandas geo series and geo data frame - with added spatial functionality

Version 1.0 brings significant performance improvements:

• Requires Shapley 2.0 with vectorized interface
• Switched from Fiona to Pyagria for faster file reading/writing
• New GeoArrow and GeoParquet support for efficient geometry encoding
• Coverage-based union operations for improved performance

Key dependencies simplified:

• Core: Pandas, Shapley (geometries), Fiona/Pyagria (file I/O), Pyproj (coordinate systems)
• Some dependencies like GDAL made optional to improve installation experience

Major new features:

• D-within spatial predicate for distance-based joins
• Full Shapley API parity
• Interactive visualization support
• Coverage-based operations for topology-aware processing

Future developments planned:

• Spherical geometry support through Spherley (Google S2)
• Curved geometry types support
• Coverage simplification improvements
• Potential Rust implementation for better performance
• Enhanced GeoArrow integration

Project evolution:

• Started in 2013 at SciPy conference
• Received NumFOCUS affiliation in 2020
• Over 200 code contributors to date
• Removed controversial datasets module in favor of neutral geodatasets
