Abstract: Instead of current two-dimensional cadastral system operating in Armenia it is proposed to introduce a three-dimensional one, which allows to reflect the DEM, natural and artificial underground spaces, three-dimensional models of upper-ground buildings, as well as the $3D$ models of both underground and upper-ground engineering and technical constructions and communication channels. Via the investment of the three-dimensional cadastral system the presentation quality of accounting entities increases, especially those which are not reflected in two-dimensional projection such as underground spaces, underground and upper-ground engineering communication channels, multi-storey residential buildings, etc. Three-dimensional cadastral system is the best way to reflect the complex objects for the application of which it is necessary to use novel technical and IT programming means.

Keywords: $3D$ cadastre, underground spaces, DEM, three-dimensional model of location, three-dimensional model of building, total station, laser scanner.
