Does Surveying and Mapping Need 3D Modeling?

Surveying and mapping has begun to use airborne lidar, ground three-dimensional laser scanner and other instruments to collect ground points (including ground features and landforms, such as building areas, sculptures, mining areas, etc. ) and establish a three-dimensional model of the ground.

The establishment of three-dimensional models of the Digital Forbidden City, Terracotta Warriors and Horses of Qin Shihuang's Mausoleum and Leshan Giant Buddha was completed with the leadership and participation of surveyors.

In close-range photogrammetry, aerial digital photogrammetry and other fields. The photos have been used for 3D modeling of the ground and establishing DTM.

Many master's and doctoral dissertations of surveying and mapping major are about three-dimensional modeling research of residential areas, campuses and other areas.
