碩士 === 國立臺北大學 === 不動產與城鄉環境學系 === 98 === Rapid development of information technology and computer technology push the revolutionary development of global spatial information industry forward. Gradually, the traditional 2D spatial information turns into the application of 3D visualization and 3D spatial analysis. Using 3D GIS with the real display of 3D landscape visualization to represent the needs of specific applications of space objects will become the emerging trends of the GIS development nowadays. In recent years, the construction of Cyber City in the world makes an upsurge; at the same time, the establishment of 3D building model is especially one of the popular topics no matter in domestically or abroad. Most of the researches participated in the construction of 3D building model which were mainly based on building exterior shape of the level-of-detail (LOD) 1 – 2. Now, the technology has become more sophisticated while the next stage of the 3D building modeling researches should develop towards LOD3 - 4 of detail building and integration of real value-added information for application development and advancement. Currently, most of the data used in 3D building modeling have several shortcomings such as old version, difficulty of obtainment and expensive and poor accuracy. Therefore, among current laws and regulations, the work of building survey in Lands Department is the only survey conducted by Government which includes building surface and cadastral location mapping information. The result map of building survey records not only the building plane and the location of spatial data, the various building plane are also accompanied by the relevant cadastral property information records. Thus, it will be one of the sources with the potential value-added applications of the 3D building information modeling data. Overall, we take the cadastre building as a starting point in this paper and propose the concept of the construction for spatial data model of cadastre building. Results of this research can be divided into three parts. Firstly, we plan an operational design to build the floor surface mapping of cadastre building with vector features, properties and topological relations which is the basis of modeling data of 3D building model. Secondly, according to CityGML of building data semantic model, we establish the substantial associations of cadastral building’s structure-objects. Then, planning an operational design to construct the spatial data model of cadastre building which successfully completes the building information model with visual information and non-geometric information by data-oriented geometric modeling approach to implement the BIM model concept. Thirdly, following the operational designs, we actually validate the construction and display the spatial data model of cadastre building. Moreover, this research and estimates for the overall experimental time and proposes the directions for the related applications of these research results. Also, this research wish to provide some suggestions for follow-up research development or related fields.
