    Statistical methods applied in evaluating the reliability of land surveying equipment
    (2014) Krupiński, Waldemar
    In order to verify whether measurements made by an electronic total station and a Leica level are systematically correct, a series of measurements by these instruments was performed on the test grid at UR Krakow, Balicka. Leica TS 02 total station was used in measurements of horizontal angles while distances were tested using the following statistical tests of identity: - horizontal angles - Smirnov-Kolmogorov test, - distance - confidence intervals testing. Elevation measurements performed by self-leveling Leica Sprinter 150M were tested by a T-test. The theoretical basis for the tests of identity and their practical application are discussed. The research concludes that the test instruments do not always meet the criteria, and in such a case, prior to measurements, they should be subjected to rectification.
