Digital Twins for National Mapping and Cadastral Agencies and other governmental organisations
In January 2022, EuroSDR will organise a workshop addressing the impact of the Digital Twin concept for NMCAs. The workshop will be held online and divided over two mornings: Friday 21st and 28th of January 9:30 – 12:30 (CET). Participation is without any costs.
Deadline for registration: 11th of January 2022.
Programme of the workshop: Click here (or read more below).
Recordings: You can watch the recordings of the presentations here.
The concept of a Digital Twin (DT) originates from industry and manufacturing. In the geospatial domain, the concept has been gaining significant momentum since it was introduced in 2012. Despite the frequent use of the term, there is not a common definition in use and, consequently, the term is used in different ways: as a digital replica of an asset in a BIM context, as a 3D city or landscape model, as a digital representation of the physical environment including its dynamic processes, as geospatial information infrastructure, etc.
Even though a single definition of a DT in the geospatial domain is lacking, there is consensus that it should be based on 3D city models, containing objects with geometric and semantic information; it should contain real-time sensor data; and, it should integrate a variety of analyses and simulations to be able to make the best design, planning and intervention decisions.
Digital Twin and National Mapping and Cadastral Agencies
The introduction of the concept Digital Twin in the geospatial domain offers a lot of potentials as it offers a comprehensive shared vision of the value of geo-information in solving societal issues. The geospatial domain has provided solutions that are nowadays assigned to the DT concept, long before the term DT was introduced. Consequently, geospatial organisations, like NMCAs and other governmental organisations, are well-equipped to address DT-challenges as how to spatially represent the current state of reality as accurately and up-to-date as possible; how to integrate geo-data from highly heterogeneous and dynamic sources and develop standards for this; and how to develop a geospatial data infrastructure to serve more than one purpose; how to generate visual rendering to stimulate serendipitous knowledge building etc.
Aim of the workshop
The aim of our workshop is to exchange experiences and plans from NMCAs and other governmental organisations on Digital Twin-related activities, to discuss the impact of the Digital Twin concept for them and to identify remaining issues, challenges as well as opportunities. It is not the aim to come to a shared definition on the concept Digital Twin but rather to discuss the meaning of the concept for governmental organisations: What are the ongoing DT-activities, what are the use cases, lessons learned, uncertainties, opportunities etc.
