基于AnGeo的城市三维导航系统设计与实现

摘要

随着地理信息系统在三维数字城市建设的广泛应用，更加逼真且信息更丰富的三维立体导航逐渐在导航领域占据主导地位。以A nGeo三维地理信息系统软件为基础，研究了三维导航系统的设计与实现，该系统不仅可以提供基本的信息查询功能，还能完成三维互动式浏览、三维地图导航以及最佳路径选择的功能。%With Geographic Information System (GIS) applications widely used in a rage of 3D digital city construction ,more realistic and informative three-dimensional navigation has gradually dominated the field of navigation .Based on AnGeo ,a three-dimensional geo-graphic information system software ,this paper studied the design and implementation of a three-dimensional navigation system , w hich can not only provide basic information query function ,but also provide the functions of three-dimensional interactive browsing ,three-di-mensional navigation and the best route selection .
