At the beginning of the autumn of 2019, we began surveying work on a major contract for the Railway Administration. The importance of the contract was also underlined by the interest of the Czech public media - the project was reported, for example, by Radiožurnál Czech Radio and Czech Television.

The aim of the contract was to make a Special Purpose Railway Map (ÚŽM) by geodetic measurements, which will be used for design work on the implementation of the high-speed line Brno - Ostrava. It was measured in the line section TU 1891, including stations Prosenice, Lipník nad Bečvou, Drahotuše, Hranice na Moravě, Jistebník, turnout Polanka, Ostrava Svinov. At these stations, the alignment and calculation of the 3D track axis was also performed. The extent of the area of ​​interest was determined by the current course of the railway line and the width of the area of ​​interest, which was approximately one hundred meters in its entire length. Routine background mapping for projects is usually carried out within the boundary of the railway land.
