Urban digital twins: DIN standard “DIN SPEC 91607” as a guide for cities and municipalities

Applications & technologies / Urban data / Urban Digital Twin

In cooperation with over 40 other experts from local authorities, associations, politics, science and business, the CUT team has spent two years developing a standard for urban digital twins. DIN SPEC 91607 “Digital Twins for Cities and Municipalities” is an important milestone for the standardization of digital twins in Germany.

Urban digital twins are digital models of cities and municipalities with a systematic reality comparison. They are based on data, technical components, interfaces and functionalities from various areas, such as geoinformation, transportation systems, environmental information or energy supply. The underlying digital infrastructure, for example an urban data platform or geodata infrastructure, provides data and enables analyses, simulations and forecasts to be implemented in applications that can be used in integrated urban development and for citizen participation in planning processes.

The introduced DIN standard “DIN SPEC 91607″ provides a basis for cities and municipalities to effectively implement digital twins, using standards and best practices. DIN SPEC means implementing a publicly available specification (SPEC) via the German Institute for Standardization (DIN e.V.). The resulting standard document ensures that the specification, as a public requirement, does not conflict with existing standards and ensures national publication.

DIN SPEC 91607″ is aimed in particular at researchers, IT experts, specialist and technical operators of digital twins or municipal data platforms as well as stakeholders in specialist fields of action. It provides a holistic overview of urban digital twins (UDZ) by addressing their development and relevant topics and classifying them in the context of municipal objectives. The aim is to create a uniform understanding of the topic and cooperation between different cities and municipalities. Central elements of the specification are the defined use cases, which are based on over 100 identified usage scenarios, including in the areas of mobility, energy, environment, safety and urban planning.

The implementation of DIN standards is an important step in enabling cities and municipalities to establish digital twins in urban development. By drawing on existing knowledge, new innovations can be initiated. We are very pleased that cities and municipalities are strongly represented in this initiative.
