How digital twins add value to urban planning

As more and more cities decide to work with a digital twin, we have selected a number of articles that describe how digital twins are created and how they can add real value. Connecting and visualizing data – and in particular geospatial data – in a digital replica of public space supports urban policymaking and helps city planners make efficient and rational decisions to improve the quality of life.

The 3D model of the city of Rotterdam

If 3D is becoming the new standard in spatial data infrastructures, how can it be used in urban settings? The Dutch city of Rotterdam, known for hosting the largest port in Europe, is preparing for this next step by developing a digital twin of the physical city. The main objective of “Digital City Rotterdam” is to improve the efficiency of urban planning and management. But at the same time, City Hall is looking for apps that will help people integrate the digital world into their real world – or will it be the other way around in the not-too-distant future?

How 3D modeling supports game-changing urban development

Accurate digital representations of cities are a game-changer in urban development. By enabling virtual modeling and intelligent simulations, they allow decision-makers to explore, test and evaluate the measures taken. Hosted on cloud-enabled platforms, these digital twins also facilitate collaboration between stakeholders who can jointly optimize outcomes that make cities smarter, safer, more liveable and more sustainable.

Using BIM data with city models

A growing number of cities are creating 3D city models to aid visualization and simulations in the city planning process. 3D city models are often extended with planned buildings. One way to facilitate this is to add simplified Building Information Modeling (BIM) models of planned buildings to the 3D city model. This article summarizes some of the recent academic and industry studies on this topic.

Digital twins for land use planning

The Dutch city of Groningen wants to follow in the footsteps of other cities like Rotterdam, Hamburg, Singapore and Helsinki by developing a 3D digital model. For the 3D Digital City of Groningen project team, the goal is for the image on the computer screen to be an exact replica of the external reality.
