Nowadays, geodetic methods are used in all segments of civil engineering. The purpose of this thesis was to find out which of the currently used methods is the most appropriate one for use in forest civil engineering. The compass method was used, as well as tachimetry and GPS. The measurements were performed using four different instruments: Suunto TANDEM, Wild RDS, Thales Z-MAX and Garmin V. For the research project, three different locations were selected with three completely different terrain configurations. At each location, 550 meters of a forest road were measured and from these measurements the site plan and the longitudinal profile for the measured road section were obtained. In addition to accuracy, which we focused on most, and the difficulties related to work with a certain instrument, the economic factor was also crucial, as this aspect is very important in forest civil engineering. Results were thus obtained that show how instruments perform in different environments. It can be seen from the collected results that in spite of certain shortcomings such as low accuracy, the most appropriate method is still the compass method, which is currently also the most widespread one. Wild RDS is useful under certain conditions which may develop during construction. Garmin V is much too inaccurate and much too prone to errors to be seriously considered in civil engineering. Thales Z-Max is not useful due to poor reception in forest areas and due to the very high price ofthe instrument. However, in the future, GPS technology which is becoming increasingly more affordable and perfected will also become important in forest civil engineering, as it is simple to use and opens new possibilities and new possible work methods.
