CityGML for Architectural Heritage


Standardization in spatial data and Cultural Heritage management is one of the main issues in this field of study and the efforts in this direction are twofold, data models and technological development. Regarding the first aspect some preliminary steps towards definition of common vocabularies and conceptual schemas for semantic classification will be analysed and discussed in order to define the open issues and the development strategies. On the side of the the modelling languages and data manipulation tools the recent standard definitions and the research efforts are starting to provide a set of application tools for the semantic and spatial data modelling and information retrieving and manipulation. An application of these notions and tools will be performed on an architectural heritage case-study and the preliminary results.

Semantic modelling

Core of the research is a proposal for an extension of the CityGML schema in order to provide a outline for the conceptual and logical modelling of an architectural heritage feature. This ADE (Application Domain Extension) draft will focus on modelling a typical architectural heritage feature that can be useful in planning restoration works and conservation state management. The aim is to to use this extension for performing diagnostics identifying current and previous phenomena, whose comparison is of capital importance for planning proper conservation. The main issues of the management of a cultural heritage archive will be taken into account in order to integrate the rich semantic features of this kind of metric data in urban cartographic databases.
