摘要

傳統的二維網格或向量式地圖已無法滿足人類使用之需求，隨著資料攫取與電腦科技的進步，地理資訊逐漸朝向三維空間資訊發展，以更真實的描述人類生活的世界。目前，數位城市之建構在全球掀起一股熱潮，其中三維建物模型之建立更是近幾年國內外研究的熱門話題。多數的研究以三維建物之視覺化為主，但三維建物不應只有建物外觀的展現，而是應該能夠整合其他相關資訊加值應用。
三維建物的建置內容複雜所須耗費的資源龐大，不同領域所建置之三維建物空間資訊如何共通共享再利用，也是眾所關注的焦點之一。國際上ISO與OGC兩大標準組織積極投入地理資訊等相關標準之制定，OGC已於2008年8月正式公布CityGML為三維城市模型資料流通標準規範。國內政府機構與學術單位也跟隨潮流積極推動地理資料流通標準之研究與制定，惟目前多著重於二維資料流通標準的制定，尚缺乏三維資料流通標準的探討。
基於上述觀點，本研究採用資料細緻層次(Level of Detial，LOD)概念建置多尺度三維建物模型。以都市發展單位之地形圖資模塑LOD1-LOD2建物模型，以地政單位之建物測量成果圖等相關資料產製LOD3-4建物模型，完成多尺度三維地籍建物圖資建置。在資料流通方面，本研究遵循國際OGC CityGML標準，並依多尺度三維地籍建物資料之內容與特性，設計一套三維地籍建物資料流通架構，並以開放式展示軟體驗證三維地籍建物資料流通的可行性。

The traditional 2D grid or vector maps have been unable to meet the demand for human use, with the progress of data mining and computer technology, geographic information gradually towards the development of 3D information in a more realistic description of where human beings have lived in. Currently, the construction of Cyber City in the world becomes a hot topic, and the establishment of 3D building model is especially the focus no matter in domestically or abroad. Most of the researches put the emphasis on 3D visualization of the building, however, the 3D building model should not only show the appearance of buildings, but also integrate value-added application of other relevant information.
In addition, due to the complexity of 3D building models, therefore it requires huge amount of resources, how to share the 3D building models built in different areas has also catch people’s attention. The two major international standards organizations ISO and OGC were actively involved in development of related standards of geographic information. OGC has officially announced CityGML as an encoding standard for the representation, storage and exchange of virtual 3D city models in August 2008. Our government agencies and academic institutions also follow the trend of the flow which aggressively promoted the exchange of geographic information research and standards development. Unfortunately, currently, we put more focus on 2D geodata standards, but lacking exchange standard for 3D geographic information.
To conclude, the study adopts the concept of level-of-detail (LOD) to build continuous four level-of-details modeling of 3D building models. Complete the multi-level 3D cadastre building model by using the topographic maps of Urban Development Organization to model LOD1-LOD2 building models and of Land Portal to structure LOD3-LOD4 building models. Regarding the data flow, the study designs a set of data exchange framework of 3D cadastral building model which followed international standards OGC CityGML and the contents and characteristics of multi-level 3D cadastral building models, at the same time to use open 3D display software to verify information on 3D cadastral building model data circulation feasibility.
