    Abstract: 近年來進行城市之三維建模時，為描述特定建模對象之地理位置與空間幾何特性，可快速並準確獲得三維資料的多元空間資訊（geomatics）技術，已逐漸帶入數位化三維建模之應用。除了空間資訊之賦予，以數位媒體來探究數位典藏，亦是實際可行並可達到資訊傳播推廣的方法，包括3D模型製作、模擬操作、動畫製作、虛擬導航、以網路為基礎的虛擬展示系統、以及文化遺產的實體計畫，皆為數位媒體於空間資訊與地理環境展示的應用，提供知識保存與擷取的另一個方式。雖然前述二種方法皆可建置欲數位化典藏城市之三維模型，但是空間資訊技術著重於量測成果之精確度（accuracy），而數位媒體方式則是以建築美學出發，強調模型之精細度（level of detail），因此，本計畫將以國立政治大學部分校區為實驗基地，分別由地形與建物二個部分探討實驗區域真實三維模型之建立。在地形的部分，採用多元空間資訊科技，建立涵蓋實驗區之高解析度且高精度的三維數值地形模型，作為欲數位化建模內容之空間基礎。接著利用數位電腦輔助設計（CAAD）建模技術，建立實驗區內各個建物之高精細度模型，達到可真實呈現各個建物之外觀與特色之目的。由於不同方法所建置之模型具備不同之特性，整合後之模型即為兼具精準度與視覺美學及真實性結合之虛擬三維模型，為數位校園典藏內容之具體有效呈現。
    City model has been proved as a useful tool in various applications. In order to improve the efficiency of model construction, and also to upgrade the quality of the 3D city models, a digitising method for constructing accurate and high level of detail (LoD) 3D model is developed. It is proposed to produce 3D terrain and building models separately, and then integrate them afterwards. The terrain model is generated using multiple geomatics techniques, in which the reference terrain is created using aerial photogrammetry technique. Additionally, the GPS RTK (Global Positioning System Real-time Kinematic) method is applied to refine the resolution and continuousness of the terrain surface. As a result, a high resolution and accuracy terrain model is obtained. Regarding the building models, a ground surveying method using total station instrument is firstly introduced to provide primitive models of buildings of interest. The computer aided design technique is then applied to upgrade the level of details of the buildings. As the terrain and building models are produced in the same reference spatial frame, the co-registration is accomplished automatically and therefore can be imported and edited simultaneously in any software environment. Once the refinement is finished, the city model which is of high resolution, high accuracy and fine level of details is achieved. The proposed method was applied in part of the campus of the National Chengchi University. The terrain model was generated using aerial photogrammetry and GPS RTK methods. The building models were produced based on primitive CAD models derived from ground surveying and the LoD was subsequently upgraded up to level four. After the integration, the accurate and high LoD 3D model was demonstrated.
