Research of Terrain 3D Visualization Method Based on IDL and ArcEngine

It is a very hot research topic in GIS, virtual reality, computer graphics, digital photogrammetry and other fields which should be researched on 3D terrain visualization. There is also an important part of the digital earth strategy in many fields in order to resolve some comprehensive problems. Trying to take advantage of IDL data processing and graphic display function and Arc Engine spatial analysis function, in the Visual C # 2005 under the environment of hybrid programming mechanism, using of component design and development of integrated development technologies analysis of terrain visualization application operating environment. It should realize the 3D digital terrain expression and spatial analysis function. The results show that the IDL and Arc Engine integrated development method applied to the 3D terrain visualization analysis software platform developed operability and extension force with strong, both in terms of space efficiency and image data analysis, development costs advantages.
