libpysal: Python Spatial Analysis Library Core¶

Weights for nonplanar enforced geometries

Introduction¶

libpysal offers five modules that form the building blocks in many upstream packages in the PySAL family:

Spatial Weights: libpysal.weights
Spatial Graphs: libpysal.graph
Input-and output: libpysal.io
Computational geometry: libpysal.cg
Built-in example datasets libpysal.examples

Note

A new Graph class is being added to libpysal. For users interested in migration from using Weights to the new Graph class, see the migration guide. For developers interested in the technical details details see W and Graph Components.

Examples demonstrating some of libpysal functionality are available in the User Guide.

Details are available in the libpysal api.

For background information see [RA07].

Development¶

libpysal development is hosted on github.

Discussions of development occurs on the developer list as well as discord.
