Anotace: The paper explores the way in which the underground objects can be measured, modelled, stored in spatial database and visualised

for purposes of the 3D cadastre. The underground objects can be represented as 3D consolidated parcels representing an independent
property that is not related to the surface parcel boundaries. The proposed solution is demonstrated for the wine cellar located in the
vineyard area Tokaj. Since the international standard ISO 19152 Land Administration Domain Model exists and allows for the registration
of 3D parcels, it is important that the used data model for storage of 3D underground parcels is based upon this standard. To model the 3D
underground parcels the LADM boundary face concept with topological encoding is used. To visualise the 3D underground cadastral map,
a new visualisation tool has been developed. The tool enables the visualisation of spatial data directly from the spatial database. When
working with a huge amount of spatial data, it is necessary to optimise the way the data in the database are queried. To optimise the loading
of data from the spatial database the vector tiles were created
