Duality of a socio-spatial system

Duality of a socio-spatial system comprises a global order constructed from the domains controlled by individuals, called a local-to-global phenomenon, as well as a global-to-local system existing over and above the domains of individuals, and expressing itself in some systems of boundaries and spaces which have a more collective or public nature.
