基于AutoCAD Map 3D地形图信息图形化技术研究——以1∶2 000地形图为例

Research the Technology for Topographic Maps Information Presented in Figures and Diagrams Based on AutoCAD Map 3D——Take 1∶2000 Topographic Maps as the Example

结合天津市1:2000地形图实际生产现状,提出一种基于AutoCAD Map 3D软件的地形图信息图形化技术。首先介绍了地物图形信息化的方式及保存方法,然后介绍了信息图形化技术方法,步骤如下:读取图形信息、绘制符号或注记、通过数据字典读取参数将其参数化。

This paper unifies the Tianjin 1∶2000 topographic maps actual production present situation,proposes one technology for topographic maps information presented in figures and diagrams,which based on the AutoCAD Map 3D software.First introduced the graphical features in the way of information and preservation methods,and then describes the technical methods of graphical information,the following steps：reading graphical information,draw symbols or notes,read parameters through the data dictionary to parameterize.
