摘　　要：在日常测绘生产过程中,经常需要查找项目范围内最新的地形图。当图幅数量大或同一幅地形图版本较多时,不仅工作效率低,而且出错率也较高。在分析大比例尺地形图图幅号规则与地形图数据更新方式及其命名规则的基础上,基于.NET开发环境,采用C#编程语言,结合数据库技术,在AutoCAD软件基础上增加地形图快速提取拼接工具,在一定程度上解决目前地形图查询程序功能不是很全面、读取调用地形图效率低,以及多版本地形图更新查询不便等问题,提高了生产效率。In the daily surveying and mapping production process,it is necessary to find the latest topographic map within the scope of the project.When the number of maps is large or there are many versions of the same topographic map,not only the work efficiency is low,but also the error rate is high.On the basis of analyzing the rules of large scale topographic maps and the updating method and naming rules of topographic map data,this paper uses C#as the development language based on the.NET development environment,combines database technology,adds rapid extraction and matching tools for topographic maps on the basis of AutoCAD software,solves the problems to a certain extent that the current topographic map query program is not very comprehensive,the efficiency of reading and calling topographic maps is low,and the inconvenience of updating and querying multi version topographic maps,and improves production efficiency.
