| Description |
Determination of accuracy of control and geodetic measurements from defective numbers and their number when surveyingand drawing up topographic plans. A sequential analysis of control and geodetic measurements makes it possible tofully use the information obtained on the quality of measurements, also it is possible due to the largest number of smalldifferences to increase the percentage of large and allowable differences and per revolution. Thus this analysis to someextent regulates the tolerances of instruction and can be more conditionally related to the final solution for controlling the quality of topographic survey. It should also be noted that the proposed quality control technique by means of asequential analysis of control and geodetic measurements can be used to control any industry whose quality is determinedby measurement standards. In topographic surveys, it is necessary to carry out control and geodetic measurementsto determine the quality of the survey, the number of which is not known in advance. In a sequential analysis foreach number of measurements, the acceptance and rejection numbers for corresponding measurements are calculatedin advance. After each measurement, the sum of the squares of the deviations of the control measurements from theiractual value or from the average of the arithmetic mean is calculated, after which this amount is compared with thereceiving and reject numbers at the corresponding number of measurements. If the sum squares of the deviation is lessthan the smallest defect number, then the control and geodetic measurements are completed and the performed worksare considered to be benign, if the sum of the squares is greater than the largest defect number then the control andgeodetic measurement continue. If, however, the sum of squares is greater than the largest defect number, then the workdone on topographic survey must be reject.
