| Abstract: | The principle,method and accuracy for the producing of 1∶5000 topographic map and its orthophoto as well as the 1∶10000 topogrophic map,which are based on the 120type non metric camera and the 1∶40000 small format aerophotoes of the area near Zhongshan Station in Antarctica,are discussed in this paper. In the case of increasing the number of control points properly and adding with some suitable weights during the exterior orientation procedure,the maxium point fitting errors are 2.2m in plane and 1.2m in elevation recpectively. The mean square error of fitting between the correspending topographic map and its orthophoto is 0.14mm. Above results can meet the needs of research and inspect work of the Antarctic area. |
