Point symbolization method of line feature 3D modeling

DENG Meng-xue,XU Zhu,WU Jun-hong(Department of Remote Sensing Information Engineering,Southwest Jiaotong University,Chengdu 610031,China)  
This paper described the point symbolization method of line feature 3D modeling.Firstly,the line feature was discretized into several points,then the 3D model of the unit of the line feature was used as point symbol to represent each point.When the size and the rotation of each point symbol were adjusted correctly,and the point models were connected as a whole.The experiments proved that this method could achieve the precise 3D modeling of the line features in some degree,and would provide a viable approach for the quick and low-cost 3D modeling of the line features.
