In recent years, technologies for digital surveys have introduced considerations on numerical modelling. Research coordinated at Laboratoire CRAI MAP - ENSA Nancy (A. Fuchs, 2006), or studies conducted at RADAAR, La Sapienza Roma (R. Migliari,2009; M. Docci,2007) have promoted a definition of formal/stylistic frameworks of representative processes to represent complex cultural contexts (A. Ferjaoui, M.L. Germanà 2014; P. Bryan, B. Blake, J. Bedford, 2012). Integration and interaction of data is persecuted (GRAVITATE Project 2015, IT Innovation Center, UK), also extendable from the archaeological scale (ARIADNE Project 2013-2017, University of Florence, IT). It emerges the objective of representation of architectural irregularities and the semantic analysis of building elements for which digital technologies have to be integrated (DM Jones, 2011; S. Parrinello, 2016).
Due to their recent acknowledgement (e.g. the Hansa 1991, Andalusian architecture 1997, Rhine Valley 2002, Pyrenean route 2003, Cluniac Sites 2005, Transromanica 2007, Cistercian abbeys 2010, Thermal Towns 2010, Charles V fortresses 2015, fortified towns of the Grande Region 2016) CHRs are poorly documented in historical and physical conditions, architectural value and operative programs of intervention and territorial management. Actual projects supporting CHRs valorisation mostly focus on a touristic, educational and training approach (HECTOR and CERTESS projects, by European Institute of Cultural Routes) demonstrating the lack of a unique and simple protocol for territorial management of CHRs sites and basins.
