摘　　要：三维地形可视化是目前众多领域的研究热点,可广泛应用于地形漫游、土地规划、三维地理信息系统等众多领域。在MAPGIS软件平台的基础上,以山西省安泽县为例,提出三维地形可视化的技术流程,详细介绍数字高程模型的构建、纹理生成以及三维场景的制作等关键技术,实现安泽县的三维场景漫游浏览、录制播放和相关的地学分析。Three dimension terrain is one of the hot research subjects at present. It can be used widely in many domains, such as terrain walkthrough, land use planning and 3D geographic information system. This paper is based on the platform of MAPGIS and takes Anze County in Shanxi Province as the example. The technical process of three dimension terrain is proposed. The construction of DEM, texture generation and the production of three-dimensional scene are introduced in detail. Tile system has realized roaming, recording, palying and geo-science analysis.
