Visual LISP语言开发与大比例尺地形图符号库设计

Visual LISP language development and large-scale topographic map symbol library design

GIS应用领域的日趋广泛,让空间数据更新成为了GIS领域的热点问题,图式符号库是空间数据采集系统的必要组成部分,对大比例尺地形图符号库的建立进行研究,具有非常重要的现实意义和应用价值。以大比例尺符号库的开发为基础,充分利用AutoCAD的二次开发平台,使用Visual LISP语言,在AutoCAD2006平台下制作大比例尺地形图符号库,详细阐述了符号库的制作全过程,实现了适合大比例尺地形图需求的点状、线状、面状符号库,并对这些符号库进行了有效的管理。克服了传统符号库设计的缺陷,有利于方便快捷地调用符号库,提高了绘图的速度、质量和效率,同时也便于及时更新地物符号。

With the wide application of GIS,spatial data updating has become a hot issue in the field of GIS. The schema symbol library is an essential part of spatial data acquisition system. It is of great practical significance and application value to study the establishment of symbol library for large-scale topographic maps. Based on the development of large-scale symbol library,using AutoCAD and Visual LISP language,the symbolic library of large scale topographic map is made on the platform of AutoCAD2006,which realizes the point,line and surface symbol libraries for the large-scale topographic maps require,overcomes the shortcomings of traditional symbol library design,facilitating the quick call of the symbol library,improves the speed,quality and efficiency of drawing,and is conducive to timely updating of topographic symbols.
