| 摘 要： | 由于大比例尺地形图数据通常采用分幅管理模式,因此数据的接边及检查工作是测绘生产过程中必不可少的工序。文章提出了一套适用于大比例尺地形图数据接边的程序设计思路,从拼图到生成格网、数据拼接、接边检查再到错误定位,最后采用人机交互的方式完成数据接边工作。文章详细介绍了用程序实现数据接边的关键技术和方法以及程序在实际应用中取得的效果。

| Abstract: | As large-scale topographic map data usually framing management,so the checking of edge matching and data splicing is necessary for surveying and mapping production.This paper presents design ideas of large-scale topographic maps data splicing program,from load data to generate grids,data splicing,edge checking,then to locate the problem,and finally finish working by Man-machine interactive ways.The article details the key technologies and methods of data splicing program,and procedures in the practical application of the results. |
