摘要：Virtual Reality based geographic information systems (VRGIS) are successfully employed today for real-time visualization in such diverse fields as urban planning, city planning, and architectural design. Today a VRGIS based software solution has to facilitate the interactive visualization of high- resolution 3D terrain data over inter- and intranet. Due to advanced software technology and innovative data management concepts, large amounts of data may be processed in real-time. Digital elevation models, high resolution orthophotos, satellite images, 3d buildings and vector data provide the real time application with the information to display excellent high quality representations of complex terrains and landscapes
