Forest maps, which are considered to be the oldest maps of our country, are inseparable part of forestry. They are also very important for forest management. Forest maps represent the state of all forests in user units. When the precision became more and more required, a lot of new methods and technologies for map creation were invented. These methods and technologies are subject matter of forest mapping. This bachelor thesis is focused on analysing methods used for obtaining spatial data in terrestrial forest mapping. The aim of thesis is to describe the process of measurement using theodolite, compass measurement, GNSS, close-range photogrammetry and terrestrial laser scanning.
