山区地形测绘中地形图精度提升与测量误差控制研究OA

This paper focuses on the accuracy improvement and error control of mountainous terrain maps,analyzes the terrain characteristics of mountainous areas and the limitations of conventional surveying and mapping technology,expounds the accuracy improvement technologies such as high-precision control networks,UAV aerial survey,LiDAR,and satellite remote sensing,and analyzes system errors and random error sources and the influence mechanism of atmospheric and terrain occlusion.A systematic error control scheme including error correction,model optimization,and quality control is proposed.The research and construction of a technical system of"accuracy improvement-error analysis-error control"suitable for mountainous areas to provide technical support for high-precision surveying and mapping in mountainous areas and ensure the reliability of relevant engineering data.
