In view of the particularity of geological conditions in the high-altitude construction area in Xizang,the difficulty of traditional large-scale mapping is that the topographic survey takes a long time and involves many personnel and equipment.And the terrain of the hydropower station is treacherous,with steep bank slopes,and only one construction access road from the early exploration on both sides is available for surveyors to use.When conducting measurements,it not only takes a long time on the road,but also has extremely low work efficiency.Given the sparse vegetation on both sides,dense debris flow,and weathered surface rock and soil,which are loose and prone to collapse,there are significant safety hazards during measurement.In order to completely solve the problem of excessive time consumption in the traditional measurement process,as there is less vegetation and less obstruction in the measurement area,which is basically exposed rock mass,the D2000+LiDAR professional drone measurement technology is used to replace the traditional total station mapping method.
