基于LISP语言的地形图自动成图

Automatic Mapping of Terrain Maps and Features Based on LISP Language

近年来随着现代化和城市化的快速发展,追求更加高效快捷的工作和生活方式已逐步成为一种趋势。测绘人员进行地形测量的过程中,主要工作可分为外业测绘、内业成图以及成果输出三大部分,其中内业成图在整个环节中是极为重要的一环。目前,地形图的绘制大多采用手工绘图,这种逐点逐线的绘图方式既繁琐又耗时耗力,这与人们追求的高效率相冲突。为了提高效率,简化工作流程,对地形图地物自动成图进行了研究。本文主要基于AutoLISP语言在AutoCAD平台上进行二次开发,实现地形图的自动成图。

In recent years,with the rapid development of modernization and urbanization,the pursuit of more efficient work and lifestyle has gradually become a trend.During the process of topographic surveying by surveying and mapping personnel,the main work can be divided into three parts:field surveying,office mapping,and output of results.Among them,office mapping is an extremely important part of the entire process.At present,the drawing of topographic maps is mostly done manually,which is tedious,time-consuming,and labor-intensive.This contradicts the high efficiency that people pursue.In order to improve efficiency and simplify workflow,research was conducted on automatic mapping of terrain maps and features.This article is mainly based on AutoLisp language for secondary development on the AutoCAD platform to achieve automatic mapping of topographic maps.
