This paper introduces the production of digital orthophoto map in complex terrain based on the actual aerial photography project. In the process of DOM production,combined with the interior and terrain chracteristics,the layout scheme of different image control points are put forward. According to the actual situation,we have designed four schemes of layout of image control points. By comparing the accuracy of production results under different schemes,the most reasonable layout scheme of image control points is selected. At the end of the paper,the characteristics of layout of image control points in aerial photographs of complex terrain are summarized.
