Ground excavation projects are almost involved in earthwork calculations. The amount of earth stone is determined by the quality of terrain expression.Through drone with load GOLD F2 GPS PPK Kit, It generated topographic expression, small workload, high software automation, reliable calculation accuracy, and calculation results are subject to survey methods and calculation methods. Its results are used in the calculation of equivalents in two flops, and the results are reliable and have visual effects.

Drone is widely used, with low cost, multitasking, good maneuverability, high efficiency, low radiation, widely used in various aspects of military and civil production. Since GPS has the characteristics of all-weather, high precision and automatic measurement, drones currently used for mapping are basically used to locate and navigate through GPS. The GPS single point positioning accuracy of the drone flight control is too bad. So RTK technology and PPK technologies are apllied on drone mapping, which both can reach cm accuracy.
