Abstract:	空間資訊的發展和應用從傳統的二維平面和靜態資料展示已拓展至三維立體和動態的分析、模擬、與其他複雜的操作及多元的應用，電腦和資訊等相關基礎科技的快速發展更為空間資訊的演進與未來的應用提供了革命性的催化效果。其中資訊視覺模擬 (visualization) 提供空間資訊系統一個直覺化的擬真操作與分析應用環境，而網路科技的進步更讓空間資訊的傳遞和應用突破地理上的限制。數碼城市 (Cyber City) 是多維空間資訊系統未來發展一個具挑戰性與開創性的課題；而數碼城市與視覺模擬和網路的結合，無疑地更能增進與拓展其效能與應用。本計畫將以三年為期，針對數碼城市空間資訊系統與視覺模擬和網路結合的相關課題進行研究。主要的研發重點將放在真實性和高效能兩大主題，以建置一高效能的網路與行動視覺化數碼城市空間資訊應用平台。研究主題包括高效能地形網格 LOD (Level of Detail) 處理機制之改良、房屋模型 LOD 機制之建立及牆面紋理影像製作、資料格式整合、漸進式傳輸之研發、以及網路和行動應用系統之研發與建置。內容則涵蓋 semantic matching, digital inpainting, COLLADA 及 X3D 三維數位內容架構、WiMAX 行動無線傳輸等先進課題。本計畫預期建置高效能的網路及行動視覺化數碼城市空間資訊應用系統，針對數碼城市中多元且複雜的各種空間資訊，提供直覺性的視覺化展示、分析、及模擬功能，並透過網路及行動運算的便利性，成為一個擬真與高效能的空間資訊整合及應用平台。透過本計畫的研發，使用者將可針對都市管理、景觀規劃、消防救災、智慧型運輸導航、虛擬城市導覽、以及其他相關應用進行視覺化的數碼城市空間資訊展示、處理、分析、模擬以及決策支援。 ; As technologies evolve, the development and applications of geoinformatics have extended from conventional twodimensional system to threeand multidimensional and dynamic aspects. In particular, Information Visualization has motivated the development of visualenabled intuitive environments for the operations and analysis in geoinformatic systems; while new generation network technologies such as 3G communications and WiMAX have further increase the availability of information exchange and delivery. Therefore, the coupling of sophisticated geoinformatic systems, visualization and network has a great potential to improve the performance and extend their applications. This project proposes to undertake the research and development in related topics for combining geoinformatics, information visualization and networking in order to implement networkbased mobile geoinformatic systems for visualenabled Cyber City applications. Emphases will be placed on improving the photorealism and performance of the systems. Issues to address include high performance LOD (Level of Detail) for terrain and building models, facade texture generation and mapping, data integration and progressive transmission, networkbased and embedded application implementation. Advanced topics will also be addressed, including semantic image matching, digital inpainting, COLLADA and X3D data schema for 3D digital contents. The results of this research project will provide uses a visualenabled, intuitive and highperformance platform for caring out advanced geospatial information demonstration, analysis, modeling and other tasks over network or with mobile devices. They will also facilitate sophisticated Cyber City applications such as virtual city touring, urban and landscape management and planning, disaster evaluation and mitigation, intelligent transportation and navigation etc. ; 研究期間 9708 ~ 9807
