Abstract
Realistic 3D technology is of great significance in the field of surveying,mapping and geographic information. This paper re-views the innovation and application of 3D technology in surveying,mapping and geographic information,including high-accuracy top-ographic mapping,urban construction planning,disaster monitoring and early warning. At the same time,the application of realistic 3D technology in GIS,visualization of geospatial data,geographic analysis and decision support is discussed. Finally,the challenges faced by the realistic 3D technology are analyzed,and its future development direction is forecasted.
