- Contents of lectures
- 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.
- Basic Geodetic Calculation: Rectangular and polar coordinates (bearing and distance). Intersection from angles. Traverses – closed traverse without orientation.
- 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.
- Angular Measurement: Horizontal and zenith angles. Optical-mechanical and electronic theodolites. Requirements for the axes of a theodolite. Errors in construction of theodolites, errors caused by the observer. Measurement of a horizontal angle in one set, measurement of a zenith angle in both positions of the telescope.
- Distance Measurement: Measurement with a tape. Optical methods – measurement of a parallactic angle, stadia range finder. Electro-optical methods – phase distance meters, distance meters measuring transit time. Physical correction and mathematical reduction of a measured distance.
- Determination of Heights – part 1: Absolute and relative height of a point, equipotential surface, true and apparent horizon of a point. Vertical datum in the Czech Republic. Direct levelling from the centre between the rods, technical levelling, levelling instruments, longitudinal and cross profiles levelling.
- Determination of Heights – part 2: Surface levelling. Underground connection by a tape. Barometric and hydrostatic levelling. Trigonometric method. Vertical refraction.
- Setting-Out of Buildings and Land Survey for Construction Industry – part 1: Setting-out plan, setting-out nets, setting-out of a general angle, setting-out of the right angle, setting-out of a point position, setting-out of a straight line.
- Setting-Out of Buildings and Land Survey for Construction Industry – part 2: Setting-out of a circular arc, setting-out of heights. Geodetical legal regulations in the Czech Republic.
- Measurements for Thematic Mapping and for as-built Documentation of Constructions: Spatial polar method, photogrammetry, laser scanning, remote sensing, GPS.
- State Map Series in the Czech Republic and Thematic Maps for Construction Industry: Map, plan, cartographical generalization, map contents, state map series – large-scale maps, medium-scale maps, thematic maps for construction industry.
- Cadastre of Real Estates of the Czech Republic: History of the cadastre of real estates, essential terms, records of property rights and other rights relating to real estates to the cadastre, survey sketch, ordering of geodetic service in the Czech Republic.
Exercises - Practical Classes
- Participation in the practical classes is compulsory at the time specified in the schedule.
- Program of lectures is posted in the classroom and on the website of the subject.
- Students must attend the practical clases in time. Late arrivals are not permitted. 100% active participation is required.
- Homework shall be made up according to the program. Homework includes technical reports, submission deadline is the next practical lesson. Submission delay will cause reduction of the final mark.
- Marks from all tests must be E or better (if the mark in the test is F, there will be one possibility of correction).
