Towards Enhancing Geometry Textures of 3D City Elements

In this research, different texture enhancement methods were investigated and proposed. Rectified perpendicular symmetric photos of 3D objects such as buildings and trees were used to generate the texture for the 3D models. Texture enhancement methods such as higher radiometric adjustment for raised surfaces and Dynamic Pulse Function (DPF) were utilized based on the form of the facade and operators’ observation along with tessellation method. The result of DPF compared with the photorealistic texturing in aspects, quality and data size. The problem of missing faces in a polyhedron and missing object within a CityGML viewer has been solved and described in this chapter. The chapter also describes the development of External code-Lists for objects of the study area which is a starting point for Malaysian Spatial Data Infrastructure (MySDI).
