This article presents the methodological framework and the first results of the research towards the spatial organization and semantic modelling of the work of the French Scientific Mission (1828-1829), the first systematic mapping of the Hellenic State. Ultimate goal of this research is to create an integrated spatial database that incorporates the geographic information from the historical maps enriched with multimedia and texts from the published work of the Mission. For this, the technological approaches suggested by the Semantic Web have been followed introducing the concepts of semantic interoperability and geographic data models in the management of historical data. Eventually, the historical map becomes the medium on which the historical data are organized as well as the narrative medium that conveys the historical knowledge to the wider public illuminating the status of the Hellenic State at the time of its establishment, from a spatial point of view.

Abstract. The scope of this research is to identify the concepts that describe cultural heritage monuments and model them with CityGML. CityGML is the most popular data model for storing and sharing semantic 3D geographic data and there is an increasing interest in its use in the Cultural Heritage field. An Application Domain Extension that covers the most important concepts for describing monuments with special focus on the ancient theatres is developed. The INSPIRE data model is reviewed and its integration with CityGML is discussed. Following the proposed extension, a CityGML model is constructed for the ancient theatre of Hersonissos in Crete. To visualize the model, it is transformed using the Generics approach.

ABSTRACT:Historical maps deliver valuable historical information which is applicable in several domains while they document the spatiotemporal evolution of the geographical entities that are depicted therein. In order to use the historical cartographic information effectively, the maps' semantic documentation becomes a necessity for restoring any semantic ambiguities and structuring the relationship between historical and current geographical space. This paper examines cartographic ontologies as a proposed methodology and presents the first outcomes of the methodology applied for the historical map series «Carte de la nouvelle frontière Turco-Grecque» that sets the borderlines between Greece and Ottoman Empire in 1881. The map entities were modelled and compared to the current ones so as to record the changes in their spatial and thematic attributes and an ontology was developed in Protégé OWL Editor 3.4.4 for the attributes that thoroughly define a historical map and the digitised spatial entities. Special focus was given on the Greek borderline and the changes that it caused to other geographic entities.
