In the process of infrastructure planning and construction, large scale maps such as topographic maps and land-use maps are used. These conventional maps are called 2 dimensional(2D) maps, where geographic objects are represented based on a 2D coordinate system. The conventional maps are suitable for representing terrain features and land-use in rural areas. However, they cannot be successfully applied to the representation of urban space comprising high-rise buildings and underground structures etc. This is because spatial data in the vertical dimension cannot be appropriately represented with conventional 2D expressions except the elevation of a terrain surface. To effectively support the complicated process of planning, construction and management of urban infrastructures, there is a pressing need for a fully three dimensional(3D) modelling of urban space, which allows geographical objects to be represented and located with a 3D coordinate system. Computer mapping makes possible 3D urban space modelling, which is far beyond the capability of the conventional 2D map.
