The record

Purpose: spopt is an open-source Python library for solving optimization problems with spatial data.
Focus areas: The project develops methods for regionalization, facility location, and transportation-oriented solutions.
Regionalization: Its regionalization methods aggregate smaller geographic units into larger regions using methods such as AZP, MaxP, Skater, and spatially constrained clustering.
Facility location: Its facility-location methods include set covering, maximal coverage, p-median, p-center, p-dispersion, and flow refueling location models.
Install options: The released package can be installed with pip or conda-forge, and a development version can be installed from GitHub.
Python requirement: The installation guide says spopt supports Python 3.11 or later.
Dependencies: The repository lists SciPy, NumPy, pandas, NetworkX, libpysal, scikit-learn, GeoPandas, PuLP, Shapely, and spaghetti as requirements.
Solver example: The repository’s facility-location example uses PuLP with the CBC solver.
Examples: Documented examples include regional income clustering, Airbnb clustering, grid clustering, and locating first-aid stations or store sites.
Support: Users can ask questions through GitHub issues, GitHub discussions, or PySAL’s Discord channel.
Security: The repository identifies itself as a public project and links to its security and quality page, but the opened pages make no security or compliance claims.
License: The repository states that spopt is licensed under the BSD 3-Clause license.
Intended audience: The project describes itself as a spatial optimization package and provides examples involving geographic clustering and facility siting.
Development: The project says it is under active development and welcomes contributors.
