The CONNECTING project, “CONNECTING Cloud Data Centre for 2D and 3D Cultural Heritage Geospatial Data: An Integrated Research Infrastructure for Data Monitoring, Preservation and Sustainability,” was presented within the framework of the Smart Maritime Network Athens Conference. The presentation took place on 18 March and aimed to provide participants with a comprehensive overview of the project, with particular emphasis on the technological framework of the Cloud Data Centre. Special focus was given to the methodologies employed for the management and visualization of 2D and 3D geospatial datasets, as well as the conceptual and technical considerations underpinning the system’s design. These included key aspects such as data security, interoperability, and performance optimization, especially in relation to sensitive geospatial information used in spatial planning and regional development contexts.
