仿真三维地图

仿真三维地图是一种特殊类型的地图数据，以其直观的三维地物代替了抽象的二维地图符号，突破了二维电子地图对空间描述二维化、三维空间尺度感差、没有要素结构与纹理信息等诸多限制，通过对真实地貌、地物的数字化三维模拟，提供给使用者一个与真实生活环境一样的虚拟现实环境。

Simulated 3D maps are a special type of cartographic data. They replace abstract 2D map symbols with intuitive 3D geographic features, breaking through numerous limitations of 2D electronic maps, including rendering spatial information only in two dimensions, poor perception of 3D spatial scale, and a lack of feature structure and texture information. Through digital 3D simulation of real landforms and geographic features, these maps provide users with a virtual reality environment that is identical to real-life surroundings.
