摘要

Increasingly, GIS technologies now are focusing to real 3D visualization to meet the needs of diverse user groups. 3D maps have also become common in many products in developed countries. This wave is expanding over the world. The type of these map products is very diverse and rich, from the map printed on paper to electronic 3D maps or maps in the internet. The products in the form of 3D map derived from database can serve many fields such as science, economics, and culture - society. Model of 3D map of West Lake area has been built on Skyline software package with two modules as Terra Explorer and Terra Builder through three main stages: 1. Data collection process to create 3D vector model; 2. Complete 3D models from the geometric model for the objects what is shown in detail; 3. Show all contents in 3D map based on 3D GIS. The virtual tours on the 3D terrain map are made for tourists so they can image the landscape and can keep strong impression in memory about tourist area forever. Besides, 3D map can also provide information on infrastructure, hotels, entertainments and other outdoor activities etc based on searching functions in GIS environment.
