| 摘 要： | 在大比例尺地形图编辑中存在大量的依比例斜坡类符号要素，包括依比例斜坡、干堤、加固岸、路堤、路堑等，该类符号是一种复合性符号，由坡顶线和坡面两部分组成，坡顶线由坡顶母线和长短齿符号组成，其中长齿长度和坡面宽度一致且垂直于坡顶母线，该符号表示复杂，编辑工作较为费时费力。利用AutoLISP语言开发斜坡类符号要素处理程序，实现符号长齿自动延伸，可大大提高该类符号编辑工作效率，提升制图表达效果。

| Abstract: | In the large scale topographic map editing has a lot of scale slope symbol elements, including the proportion of slope, embankment, reinforced shore, embankment and cutting. The symbol is a kind of composite symbol, two parts of slope line and slope. Slope line is composed of slope top bus and length symbol, long tooth length and slope width and perpendicular to slope bus. The symbol is complex, editing work is timeconsuming and laborious. By using AutoLISP language, the slope class symbol element processing program can be developed, and the automatic extension of symbol long teeth can be realized. It can greatly improve the efficiency of such symbol editing and improve the effect of drawing expression. |
