摘要
从空间信息中更快、更多地获取用户所需信息以辅助完成工作是GIS系统的根本目标。从空间认知的不同模式出发,分析了三维空间可视化的两种趋势;考虑到不同人群认知能力的差别,对用户进行了具体的分类,结合用户的使用场景与目的并在可视化实现中对比例尺与LOD进行分析,提出了一种适人化三维GIS模型。
The ultimate goal of GIS is helping users acquire more geographical information in shorter time to facilitate their work.Based on the patterns of spatial recognition,this paper analyses two developing trends of 3D spatial visualization.Then users are classified into different groups by their recognizing ability.Combining users'scenario and aims of work,the factors of scale and LOD are considered in the implementation.Finally,this paper proposes a humanoid model of 3D GIS based on above analysis.
