This study proposes a method of parametric modeling by using DOM and LiDAR point cloud date, aiming to respectively analyses the features of ground object model and obtain partial feature point coordinates of ground object. Besides, a specific method of triangle network connection is adopted to build a 3D ground object model and finally maps the model to display. The method has following advantages: efficiency and fast; high degree of automation met the requirements of exhibition of the railway 3D GIS. Meanwhile, based on the model built by point cloud date, huge workload of placing ground object model can be reduced during the latter period of inputting 3D terrain.
