PySAL: History, Applications & Science

PySAL (Python Spatial Analysis Library) is an open-source Python library and ecosystem for spatial data science. It provides tools for geocomputation, spatial analysis, spatial statistics, spatial econometrics, and geovisualization. The project is distributed as a metapackage and as a set of smaller packages that provide tools for spatial weights…
