Research on 3DGIS visualization technology

摘要

Using 3D visualization technology, environment and objects in the nature can be represented in a dynamic and intuitional way. It improves the effect of perceiving terrain and environment, which is a current research trend of geographic information system. Through the analysis of 3DGIS and related visualization technology, the paper concluded the research status of 3DGIS related technologies. Based on the research of 3D terrain, terrain features and real time display technologies, the 3DGIS visualization related technologies were concluded. The future development orientation of 3DGIS technology was also analyzed in the paper. The research concludes related works and orients the future work of 3DGIS technologies.
