ON THE ERROR PROPAGATION, ACCURACY ESTIMATION AND QUALITY CONTROL IN THE HIGH PRECISION LEVELING

Liang Zhenying, Mou Xiuzhen, Li Ming (Chinese Academy of Surveying and Mapping,Beijing, 100039)  
Based on the theory of statistical correlation and the research results of the propagation of the error and the estimation of accuracy, the allowable error of the total means square error per kilometer and the quality control in precision leveling is investigated in the paper. The unbiased formula of the total mean square error is also given in light of the figure correlation.
