  1. Introduction: Geodesy, surveying. Shape and size of the Earth, reference surfaces. Cartographic projections (Cassini-Soldner's, Křovák's and Gauss-Krüger's projections). Substitution for a sphere by a plane.
  2. Basic Geodetic Calculation: Rectangular and polar coordinates (bearing and distance). Intersection from angles. Traverses - closed traverse without orientation.
  3. Evaluation of Precision and Accuracy of a Measurement: Accuracy, precision. Errors - mistakes, systematic and random errors. Processing of measurements with the same accuracy. Law of standard deviation propagation.
