摘　　要：最新发布的2017版地形图图式在原有图式的基础上对部分符号进行了改动和综合取舍,现有低版本CASS制图软件符号库已不能满足新的绘图符号要求。本文通过对符号库系统文件结构深入解析,结合新版图式符号实例,实现新版图式中点、线、面以及复合地物符号的自定义编辑,为绘图软件的工具菜单和符号库的更新提供有力保证。The latest 2017 edition schematism of topographic map has changed and comprehensively selected some symbols on the basis of the original one.Existing symbol library of low-level CASS mapping software can not meet the new drawing symbol requirements.In this paper,through the in-depth analysis of the symbol library system file structure,combined with the new version of the schema symbol instance,the custom editing of the dot,line,polygon and composite feature symbols in the new version of the schema is provided,which provides strong guarantee for the tool menu and symbol library update of the drawing software.
