This paper points out that the accuracy of topographic maps produced by aerial photography is usually positively correlated with the resolution of the obtained images,proposes to combine the technology of ground imitation flight and oblique photography to produce the topographic map of a high mountain areas.In order to verify the feasibility of the proposed scheme,this paper takes the topographic map data of a certain area as an example,explains the key technologies in detail,and tests the accuracy of the topographic map.The results show that the topographic map obtained based on the scheme in this paper can meet the accuracy requirement of 1:500 topographic map,and the research in this paper is expected to provide experience reference for data producers in the same industry.
