The aim of the study course is to promote understanding of the role of geodetic and land surveying methods in earth and environmental sciences, a set of applied instruments, hardware and aids, their methods and techniques and desired results, data processing obtained with geodetic methods, presentation of the results of measurements on topographic plans and maps and methods to control the accuracy and precision of the results. Description of course tasks: 1.to give an insight into the historical and contemporary role of geodesy as a science and its relation to other fields of science, 2.to introduce with coordinate and altitude systems, their application in geodesy in the world and in Latvia, 3.to introduce with the magnetic field of the Earth, its measurements and significance, 4.to characterize different methods of horizontal and vertical surveying, including angular, distance and elevation measurements, the instruments and their design required for performing geodetic tasks, 5.to analyse the accuracy and use of data from different survey methods and instruments, 6.to provide theoretical and practical skills on the preparation of cartographic materials, the development of geodetic network, tachymetric surveying, field data processing, data import into CAD and GIS software, preparation of topographic plans, 7.to raise awareness of the accuracy and necessity of geodetic networks, regulatory frameworks in Latvia in the field of geodesy and land surveying, the possibilities of using the GNSS base station network, in the context of geodetic and GIS data collection. The study course is taught in Latvian.
