摘　　要：专题地图主要由地理基础和专题内容组成,地理基础作为编制专题内容的骨架,表示专题内容的地理位置及与地理环境的关系。传统的专题信息主要以二维专题地图的形式展现,依靠GIS的制图表达和空间分析能力来展示与专题内容相关的信息。基于三维空间的专题信息展示,除了集成影像、地形、矢量、模型等基础地理数据,还可以借助地理空间位置丰富专题业务数据,表达社会化多媒体信息。同时借助三维空间展示效果,以时间轴的形式反映空间范围内的信息动态变化。本文探讨了借助三维GIS,融合地理基础信息及社会媒体信息,形成多维尺度的信息展现方式,有序直观的反映整个专题的内容,丰富专题信息的表达效果。The thematic map is mainly composed of geographical basis and thematic content.Geographical bases as the skeleton of drawing up the thematic content indicate the location of the thematic content and its relationship with geographical environment.Traditional thematic information is mainly exhibited in the form of 2D thematic maps.It depends on the graphic expression of GIS and spatial analysis ability to show the information related to thematic contents.The 3D thematic information exhibition can rich the business data and express the social multimedia information with the aid of geographic locations as well as integrate the basic geographic data such as images,terrain and vector elements,models.Simultaneously,it can reflect the dynamic change of information within spatial range in the form of timelines with the aid of 3D display effect.This article discusses the display modes of multidimensional information by integrating the geographical information and social media information with the aid of the 3D GIS system,which can orderly and intuitively reflect the content of the whole theme and also can rich the display effect of thematic information.
