摘要
三维地理信息技术是目前GIS科学发展的新趋势之一。它以三维虚拟可视化技术给用户展现地理空间现象,不仅能表达空间对象间的平面关系,而且能描述和表达他们之间的立体关系。3DGIS平台仿真展示地形(地貌)、地质体的三维场景,地质三维可视化应用,能便于地学工作者深入分析地质体的空间展布规律,尤其是通过视点的变化,拓宽观察地质体空间展布的视野。
The geographical information technology of the three-dimension is one of the new trends of scientific development of GIS at present. It represents the geographical space phenomenon {or users with the fictitious visual technology o~ the three-dimension, can not only express the level relation among the space targets but also can describe and express the cube of rela- tion between them. 3D GIS platform emulation shows the three-dimensional scenes of ground form, geological body exhibition cloth, the visual application of the geological three- dimension, use the family to experience the environment from a lot of angles, produce the feeling on the spot in person. The three-dimension of the geological phenomenon is visual can learn the space exhibition cloth law that workers analysed in depth the geological body bene- fitting, especially through the change of the view point, widen the vision which observes the space exhibition cloth of geological body.
