Aiming at the verification of the total station commonly used in farmland basic mapping, the traditional method is carried out according to the method of the national verification regulation JJG 703-2003. There are difficulties such as the difficulty of the site selection and construction of the baseline field of the standard, the tedious verification process, the complexity of data post-processing and so on. Based on the analysis of the ranging error of the total station, this paper proposes that the baseline field is transmitted to the high-level total station through the 21 segment combination comparison method, then through the three-stage comparison method, the quantity is transmitted to the verification scheme of the low-level total station. The experimental results show that this method has high verification efficiency, convenient operation, and accurate and reliable verification results.
