Moscow Metro is a subway system. This 3D-model is built using public information on geographic coordinates of stations and their depths. Latitudes and longitudes of stations are evaluated into local coordinates with origin in the «zero kilometer point» in the center of Moscow. Depths of stations are displayed taking into account local heights of ground surface above sea level. Thus, the model indicates real positions of stations in 3D space. The scale of depths is magnified times compared to the scale of flat coordinates.
