Faculty OTB Research Institute for the Built Environment Department OTB Onderzoek Date 2010-12-01 Abstract GIS is changing rapidly its face with the advancement of computing technologies. From merely a 2D representation of real world features, it is moving to present more and more applications in 3D formats. Today 3D GIS is an essential way of handling the spatial data in urban planning. In cities where every inch of land is measured and is consumed by construction of buildings, mere 3D visualisation of the features is not enough. For certain applications which require extensive details of the building architectures, it becomes a prerequisite to maintain a topological accuracy among the features to be represented. This paper describes the process of topologically correcting 2D features to serve as the basis to create topologically correct 3D city models. The 3D model is created from an existing 2D large-scale topographic map and LIDAR height data.
