It is growing interest of creation topological 3D GIS models for many areas such like cadastres, urban planning, environmental monitoring, telecommunications, etc. The article presents problems and possible theoretical solutions of creation 3D topological GIS model and calculation topological relationships. The main idea is to use object-oriented model based on simplexes and graph theory, to calculate possible topological relationships using 9-intersections model and to compare with results obtain by other researchers.
