With the fast world population growing, the efficient use of land properties became of great necessity. In this context, the traditional two-dimensional (2D) cadastral management mode cannot satisfy the need of current 3D land use and 3D urban planning (Guo et al. 2014). So, developing a 3D cadastral system is a very promising solution for land administration. However, the development of such a solution can be faced to some challenged issues related to economic, legal, technical and organizational aspects. In this paper, we present some basics about the 3D cadastre in Land governance.
