Studies on Dynamic Segmentation in GIS
地理信息系统中动态分段技术的研究

Dynamic Segmentation is a new technique in the analysis,displayingand mapping of lines in GIS.In view of GIS application in the transportation in-formation management,this paper discusses the origin of dynamic segmentation andthe characteristics of attribute data base for it and gives the algorithm for its im-plementation. Taking the mutual querying between spatial data and attribute dataas an example,it demonstrats the application of dynamic segmentation,and dicus-ses the related algorithm and the command format.
