Accuracy Analysis of Geodetic Measurements

The analysis of the accuracy of geodetic measurements addresses the relationship between the determination of internal and external measurement accuracy, taking into account the influence of the accuracy of measurements of the geometric parameters required for individual methods of determining the position of a point on the Earth’s surface. Internal measurement accuracy is the degree of agreement among measured values obtained by repeating a measurement procedure multiple times under specified conditions, while external measurement accuracy is the degree of agreement between the measured value and the true value—or the value considered to be true. Measurement accuracy is the probable degree of agreement between the measured result and the true value of the measured geometric parameter, which is a simple geometric figure onto which the shapes of building structures are projected for stakeout and control measurements.
Expertise: Students will acquire advanced knowledge in the field of geodetic measurement accuracy, particularly regarding intrinsic and extrinsic accuracy, actual and mean errors, the law of error accumulation, and the principles for determining 2D positional accuracy. They will understand the principles of analyzing the accuracy of individual methods for determining point positions and the factors influencing the resulting accuracy.
Professional Skills: Students are able to mathematically evaluate the accuracy of geodetic measurements and determine the influence of the accuracy of individual geometric parameters on the resulting position of a point. They can analyze the accuracy of the polar method, forward and backward intersection, the method of intermediate stations, the traverse method, rectangular coordinates, and other intersection methods, and compare them with one another.
General Competency: The student independently and responsibly decides on the choice of method for determining a point’s position, taking into account the required accuracy, the nature of the task, and the measurement conditions. They provide a professional justification for the choice of surveying method and the optimal conditions for its use, critically evaluate the impact of individual sources of error and the limitations of the procedures used, and take responsibility for the quality and accuracy of the results of the accuracy analysis. They are able to coordinate professional considerations leading to the optimization of the surveying procedure and clearly communicate conclusions regarding the accuracy and suitability of the proposed solution.
