UMnD

Urban Modelling in Higher Dimensions


Urban modelling in higher dimensions, UMnD for short, is a project funded by the ERC Starting Grant ERC-StG-2015, which awarded 1.5 million euros to Jantien Stoter for a five-year research project. It started in September 2016 and is scheduled to run until August 2021. The Amsterdam Institute of Advanced Metropolitan Solutions funds the implementation of the UMnD research results for urban applications in Amsterdam.

Objective

3D geographic information about urban objects (buildings, roads) is needed to monitor and control processes within modern urban areas (noise, flooding, energy demand-supply). However, each specific process requires 3D data with its own specific semantic and geometric Level of Detail (LoD), and current approaches require enormous manual efforts to collect general-purpose 3D data and to transform it to make it suitable for a specific application.

In this project, we will develop a fundamental solution for providing 3D data at application specific LoDs. For this, we will use an innovative method that goes far beyond the state-of-the-art by introducing higher dimensional (nD) mathematical models, which will enable us to to enforce consistency by modelling the LoDs as an extra dimension to the 3D spatial dimensions in an integrated 3D+LoD (4D) model.

We have defined three key research lines for the project: (i) a groundbreaking extension of 2D cartographic generalisation solutions to 3D, enabling us to automatically derive application-specific coarse 3D data from fine 3D data; (ii) embedding multiple 3D city models at different levels of detail into a single 4D model; and (iii) “slicing” operations that extract custom 3D cross-sections of the 4D model. By combining the results of these three lines of research, we aim to generate error-free 3D data at application specific LoDs.

If successful, the 4D approach opens a new horizon for modelling parametrisable aspects of urban environments, which may establish new modelling paradigms in the future.
