Spatial network analysis software packages are analytic software used to prepare graph-based analysis of spatial networks.
They stem from research fields in transportation, architecture, and urban planning.
The earliest examples of such software include the work of Garrison (1962), Kansky (1963), Levin (1964), Harary (1969), Rittel (1967), Tabor (1970) and others in the 1960s and 70s.
Specific packages address their domain-specific needs, including TransCAD for transportation, GIS for planning and geography, and Axman for Space syntax researchers.
Many were developed in academia and are freely available or freely available for academic research.
