Research on Construction of Coal Mine Topographic Map Based on Aerial Photogrammetry
The construction of traditional coal mine topographic maps requires a large amount of manpower and material costs,and is inefficient,making it difficult to achieve information application.With the continuous development of drone technology,aerial photogrammetry has become the mainstream method for constructing topographic maps.For this purpose,a coal mine topographic map was constructed using aerial photogrammetry technology using a coal industry limited company in Shanxi Province as the survey area.Based on the characteristics of hilly and mountainous areas with significant differences in vegetation density in the survey area,the planning and requirements of aerial photogrammetry in the survey area were elaborated,and the practical application of aerial photogrammetry technology in the field of topographic map construction was realized.
