基於現代化戰爭中，隨著戰爭型態不斷的改變，戰場環境資訊獲取顯得日漸重要，未來台灣所面臨的作戰型態，將是以「防衛固守」爲目標的城鎮防禦作戰，因此，國軍亦將城鎮作戰列爲模擬演練之重點。然而爲了有效在城鎮戰場取得地形、地物的空間資訊及其分析，本研究將利用三維(3D) GIS技術，以航空數位影像及攝影測量爲理論基礎，運用數值高程模型、紋理映射、圖層套疊及拓樸關係的電腦幾何建構模式，建構仿真的城鎮戰場平台。同時利用GIS可視域分析模式，結合城鎮作戰準則，進行戰場空間評估分析，可迅速提供指揮者利用模擬3D戰場環境，評估兵力或武器部署之作戰決策。

In modern war, with the war type changing constantly, it is important day by day to obtain environment information in battle fields. The operational challenges that Taiwan Military units are facing in the future will be fighting for urban defenses. Consequently Taiwan Department of Defense has classified urban operation simulation and drill as the focal point. But in order to obtain topographic information, surface features and analysis in the urban battle field effectively, this research utilized 3D GIS technology with the aerial digital images, photogrammetry as the theoretical foundation, and Digital Elevation Model, texture, layers of digital maps and topology of computer geometry to build the platform for urban battle fields. Using viewed analysis model in GIS and the urban operation rules for preceding the battle field assessment commanders can be provided rapidly the 3D battle field environment information to make decision of armed deployment.
