Abstract

In a system for arranging survey points in field operation with a ground electromagnetic instrument, the position information of survey lines and survey points are planned and downloaded to an aircraft in advance. The survey lines and one survey point among survey points planned in advance is selected and the coordinate information of the survey point is acquired. The aircraft is controlled to fly to the physical geographic location of the survey point according to the coordinate information of the survey point in conjunction with positioning information acquired in real time. The aircraft hovers above the physical geographic location of the survey point and projects a predetermined indication mark to the ground. The detection instrument and electric field sensor are deployed at a first position indicated by the indication mark, and the magnetic field sensor is deployed at a second position; such a process is repeated till all of the planned survey points are arranged.
