本研究旨在透過虛擬實境及地理資訊系統的結合，建置人機互動之地理教學平台。首先透過全球定位系統的輔助，以包含豐富文化與自然資源之台北縣淡水鎮爲例，完成資料庫之外業行動調查，並利用地理資訊系統的強大空間模組做相關資訊的連結與展現。再以遙感探測技術結合數值地形模型及3D繪圖軟體，完成研究區內3D地形及地物之建置，最後將其整合於虛擬實境互動軟體中，建置3D虛擬實境地理教學平台。並針對76位中小學社會科領域相關教師進行系統測試與訪談，結果顯示本系統確實有助於改善傳統地理教學之不足。本研究藉由虛擬實境的擬真性及互動性，以及地理資訊系統強大的空間展示和分析模組，期能讓地理教學融入虛擬實境互動中，讓親臨其境之感帶來教育性及空間性概念。希望本研究可使當前大多停留在2D紙本教材的地理教學，能有更具體且豐富之互動學習環境。

This study aims to establish a man-machine interaction teaching platform of geographic information via the integration of virtual reality and geographic information systems. Firstly, with the global positioning system technology, we created a field investigation database based on the cultural and natural environment of Tamsui town in Taipei County. The database was setup by geographic information systems to demonstrate the information. Then, by integrating digital terrain modeling, remote sensing technology and 3D sketch software, we setup the 3D geography and 3D buildings of the study area. Finally, the 3D geographic information teaching platform was established by virtual reality interaction software. Then we proceed to a series of tests and interviews with seventy-six social studies teachers in elementary and junior high schools, and the result shows that the system could bring a distinct improvement in traditional geography teaching. The most valuable achievement of this research is to build a customized virtual geographic information platform with the aid of 1) the simulative and interactive feature of virtual reality; and 2) the powerful demonstrations and the analytic functions of geographic information systems. The platform offers an educational and spatial environment conducive to learning geography. Furthermore, we demonstrate the features and feasibility of the platform and show that how the teaching of geography can be done in an interesting way to improve the traditional 2D paper teaching.
