基于AutoCAD的上海市地形图管理系统设计

The Design of Shanghai Topographic Map Management System Based on AutoCAD

地形图通常以分幅的dwg格式存储,使用时需根据工程项目范围找出对应的若干张地形图并拼接成一块整图。如果工程范围较大或需要查找指定年份的历史地形图,查图和拼图的效率较低。因此,文章结合地形图分幅及编号规则分析,设计了一套基于AutoCAD的上海市地形图管理系统,系统借助AutoCAD ObjectArx.NET二次开发技术,可在AutoCAD软件中自动插入指定位置的地形图,具有多种调图功能,支持路网及接图表的叠加,以及插入指定年份或最新地形图,有效地提高了地形图查图和拼图的工作效率。

Topographic maps are usually stored in the format of segmented dwg.When used,several corresponding topographic maps should be found according to the scope of the engineering project and spliced into a whole map.If the scope of the project is large or you need to find the historical topographic map of the specified year,the efficiency of the map search and splice is low.Therefore,combined with the analysis of topographic map framing and numbering rules,this paper designs a set of Shanghai topographic map management system based on AutoCAD.With the help of AutoCAD ObjectArx.NET secondary development technology,the system can automatically insert topographic maps of specified locations in AutoCAD software.It has a variety of map adjustment functions,supports the superposition of road network and graphs and the insertion of the topographic maps of the specified year or the latest year,which effectively improves the search and splice efficiency of topographic maps.
