地球物理勘探一般按照一定的测网进行观测;而观测点及异常位置的正确程度,主要决定于物探基线测量的精度。在物探测量中,是三角点控制基线,基线控制测线,测线控制观测点,因此了解基线测量的误差来源对于提高物探数据的质量是有重要意义的。 Geophysical prospecting is generally observed according to a certain network; and the correctness of observation points and anomalous locations depends mainly on the accuracy of geophysical survey baseline surveys. In the geophysical survey, it is the triangle control baseline, the baseline control survey and the survey control observation point. Therefore, it is important to know the source of error of the baseline survey to improve the geophysical data quality.
