The thesis deals with surveying work during the planning and construction of telecommunication network and subsequent entry into the cadastre of public infrastructure. Surveyor starts to work in the planning stage, because the constructor needs the correct underlay for the planning. At the same time surveyor provides a geodetic survey of the existing situation of the terrain. Then construction designed lines and facilities have to be staked out in nature. After the completion of construction the recording of new facilities, surveying plan and entry of new facilities in the operator's records and cadastre of public infrastructure have to be done. In addition to all these works, the surveyor often must undertake the following tasks. For the purposes of obtaining an easement on certain property surveyor conducts the information marking. During construction often comes to moving or destruction of the existing milestones. Surveyor gives these milestones back to its original state. After completion of the work surveyor for various reasons (renovation of roads, construction of new buildings, etc...) and on the basis of already recorded data stakes out lines and facilities of telecommunication network again. A complete description of works is in this thesis presented and with pictures and attachments illustrated.
