A real time 3-dimensional transformation method for 2-dimensional building data and an apparatus therefor, and a real time 3-dimensional visualization method for 2-dimensional building data and an apparatus thereof by using the same are provided to maintain the feeling of the 3-dimensional visualization and to enhance the intuitive recognition of a user. A present position detection member(100) detects the present position of a navigation system by means of a GPS(Global Positioning System). A navigation database(200) stores data to be displayed to users in the navigation system. A building control member(300) converts the 2-D(Dimensional) building data into 3-D building data and controls information for visualizing. A distance detecting member(310) determines a relative distance between the building for performing the 3-D conversion and the reference position.
