A scale plan is one of the main products in the railway industry. For creating electronic versions of such plans, GIS allowing to combine heterogeneous data obtained by surveying instruments and survey complexes is increasingly being used. GIS has a wide functionality and allows its expanding due to the possibility of developing user software modules, thanks to which it is possible to significantly speed up the process of surveying data processing in order to create scale plans. The results of

... enerating the scale plan according to the survey data obtained with a hardware-software system "Profile-M" and UAV are described. It is discussed that UAV data can reduce the amount of field measurements performed by the hardware-software system, as well as become sources of control measurements for terrestrial surveying.
