| 摘 要： | 基于AutoCAD软件平台,阐述了点、线及面等类型基础地形图符号的设计与创建过程。在对空间数据进行预处理和数据转换的基础之上,根据地物编码表与符号编号之间的对照关系,建立了空间基础数据符号库。最后,运用Autolisp二次开发语言设计了空间基础数据的符号化步骤,完成了点、线及面等地理要素的符号化表现,并实现了地形图图外整饰内容的合理配置。

| Abstract: | Based on the AutoCAD platform,the paper illustrates the design and making of symbols referred to three types including point,line,and area.After the preprocessing and transformation of the spatial topographic data,the symbol library depended on the relationship between feature code and symbol index has been created.Using the in-line programming language Autolisp of AutoCAD,one applicable flowchart for features symbolization has been designed.Following this chart,the representation of spatial topographic dat... |
