| Summary: | 碩士 === 國立中央大學 === 資訊工程研究所 === 91 === 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.
