Information Collection and Management

Introduction The spatial representations of our world, both natural and built, are being increasingly described using 3D geospatial models. The creation of accurate, photorealistic 3D city models that can be used in real-world applications still remains a challenging problem in spatial information science. Three-dimensional modelling is required in applications as diverse as urban planning, disaster management, asset management, environmental monitoring, navigation and intelligent transport systems. Such applications call for efficient methods for the creation, storage, retrieval, analysis and visualisation of 3D city models. This research relates to the NIMLI project in that land information can be managed and maintained in a virtual 3D platform.
