【Abstract】 With the development of GIS(Geographic Information System ), 3-D visualization of terrain and other geographic features become more and more necessary. This paper studies on the technical characteristics of ArcObjects and explore the potential of its application to 3D visualization. The conceptual approach and prototypical practices have been researched with the combination of VB and ArcObjects. The main work is focused on : the display of large data volume of 3-D terrain of a city by ArcObjects: developing a prototype system of 3-D flight simulation and applying it to the terrain of city. These applications are successful. These experiments in the practices show that ArcObjects can be easily used to build up complex 3-D GIS in a short period.更多还原
