| Abstract: | Combined with the task of 1:10000 digital mapping, this paper analyzed the process of three-dimensional model building with data of POS supported aerial triangulation, discussed the main technical points in the process, including the camera file creation, the air line building, the control points importing, the height anomalies model importing and manually editing in the process of relative orientation. Finally precisions of the three-dimensional model built are tested, results showed that precisions meet the requirement of 1:10000 digital mapping. |
