A Study on Generation for 3D Geospatial Data using Digital Photogrammetry System
Aerial photogrammetry, which is one of the most frequent used technologies in mapping and surveying,has been appreciated for its work flow and accuracy to generate 2D and 3D geospatial data. In aerial photogrammetry, more than two photographs are taken over the same target area in different position with overlap. Using these photographs and minimum number of ground control points, 3D stereo model is so formed that the ground surface in reality is reconstructed through analogue/analytical plotter or digital photogrammetry system. In case of digital photogrammetry system, 3D geospatial data could be automatically extracted in partial Recently, in the advent of aerial digital camera such as ,4DS40 and DMC, digital photogrammetry system will be in the first place for generating 3D geospatial data. In this paper, we experimentally generated 3D geospatial data using digital photogrammetry system in the aspect of work flow.
