3D city model of Aalen; [3D-Stadtmodell Aalen]

Abstract

This article presents a three-dimensional city model of Aalen. Digital city models can bring together building geometry, terrain and other urban information in a visual representation that supports communication and planning. Their value depends on data accuracy, appropriate detail and how well the model reflects the intended use. A 3D model can help users understand spatial relationships that are harder to interpret from conventional maps, including building form and the arrangement of urban spaces. The topic illustrates the practical role of geospatial modelling in local planning, visualisation and the communication of information about a city.
