The relationship between the cultural value of architectural heritage and its spatial features is straightforward.
3D spatial information systems are very effective to store such information and to support its analysis.
Mainly two approaches are proposed by literature, notwithstanding the still existing challenges, and their integration is a powerful opportunity:
the Heritage Building Information Models (HBIMs)
or the archiving of the information in 3D city models.
Many related issued need are object of study:
1) How to suitably represent architectural heritage and historical cities in 3D city models?
2) How the information from HBIM can integrate the representation of architectural heritage and historical cities?
