AutoCAD二次开发在大比例尺地形图更新中的应用研究

Research on the Application of AutoCAD Secondary Development in Updating Large Scale Topographic Maps

通过大比例地形图更新项目,以AutoCAD为平台,以AutoLISP为开发语言进行了一系列功能设计开发。功能实现了正射影像快速插入、数据图层快速切换、重复实体图形的快速检查和删除等功能,极大提高了地形图更新的生产效率和成果的检查能力,以及图形的自动化处理能力。

Through the large scale topographic map updating project,this article uses AutoCAD as the platform and AutoLISP as the development language to carry out a series of functional design and development.It realizes the functions of fast insertion of orthophotos,fast switching of data layers,fast checking and deletion of repeated entity graphics,etc.,which greatly improves the production efficiency of topographic map updates and the ability to check results,as well as the automatic processing capabilities of graphics.
