| dc.description.abstract | 3D視覺化及動態模擬技術可以讓人們更方便、更有效率地以電腦模擬的方式來探求新知。當我們將此技術與地理空間資訊及物件屬性資料結合在一起時，即可創造出一個有效率的動態虛擬環境。這樣的環境將可應用於環境展示系統、軍事模擬系統及三維地理資訊系統中。
地理空間資訊及物件屬性資料的種類繁多且格式複雜，為了讓此虛擬環境中的模型及屬性資料能夠與其他系統的資料互通，且達到良好的應用效果，我們以SEDRIS的規範來創造此虛擬環境。
在SEDRIS中所規範的資料描述模式，主要是利用軟體工程的技術來清楚地描述、定義我們真實環境中的物件。我們將以此資料描述模式來描述虛擬環境中的3D物件及它們的屬性，並以此方法來建構3D的虛擬環境。
在本論文中，我們將以SEDRIS的應用程式介面系統及軟體發展工具集來開發以SEDRIS為基礎之虛擬環境的編輯器及瀏覽器。另外，對於3D地理資訊系統的應用，我們也開發一個屬性查詢子系統。 | zh_TW |
| dc.description.abstract | 3-D visualization technology offers facilitative and efficient functions to acquire new knowledge. The technology combining geographic information systems (GIS) provides replicating real-world objects maximizes the user’s experience within an interactive synthetic environment. Moreover, queries in GIS play an important role. Traditionally, queries are mainly in two-dimensional style. It will be a great challenge to directly present queries for GIS data within a 3-D synthetic environment.
In this paper, we presented a platform to construct a virtual environment using synthetic environment data representation and interchange specification (SEDRIS) and provide a system to query attributes of the objects contained in the virtual environment.
The data representation model of SEDRIS is a software engineering technique for unambiguously articulating information about the data within our real world. In this study, we will utilize this technique to unambiguously represent 3-D objects and its attributes to archive a virtual environment construction. | en_US |
