This paper takes the Maodi coal mine in the east foothill area of Luye Mountain,Aojiawan Township,Xing County,Shanxi Province,as the study area to carry out the comparative analysis of elevation based on unmanned aerial vehicle(UAV)inclined photogrammetry.The UAV images are modelled in three dimensions to obtain a three-dimensional model.The elevation data are generated and elevation point matching is performed.The elevation comparison analysis is carried out for each area under different flight altitudes,and the parameters of each area are counted to analyze the terrain characteristics and elevation change characteristics of different areas.The difference of elevation data is calculated,the parameters of the difference data are calculated,and the reasons for the data error are analyzed.The analysis area is selected for subsidence analysis.
