3D MODELING OF TRANSPORT INFRASTRUCTURE OBJECTS
In article are described the main tasks of 3D modeling of transport infrastructure. The meaning of information units in three-dimensional modeling is described. A new concept of three-dimensional information units has been introduced. The difference between information items and real information items is shown. The value of visual modeling in three-dimensional spatial modeling is shown. The difference between object and situational three-dimensional modeling is shown. It is proved that three-dimensional modeling of transport infrastructure objects is situational. 3D modeling is an integral technology in modern transport management.
