基于Visual Basic的大比例尺地形图数据接边检查程序的实现

Realization of Edge Matching Program of Large-scale Topographic Map Based on Visual Basic

在大比例尺地形图的编绘过程中,数据的接边检查是测绘生产过程中的重要工序之一,为了减少地形图接边的错误率和提高接边效率,文章对大比例尺地形图接边检查程序进行了研究,主要采用Visual Basic语言编程实现了大比例尺地形图接边的检查。程序基本流程为数据拼图、生成内图廓、接边检查、错误信息标记、人机互动改正过程,并详细介绍了编程的关键技术。

In large-scale topographic map compilation process, the edge matching of data is one of the important links in surveying and mapping production. How to reduce the workload and improve work efficiency is the direction of this study. The paper mainly uses Visual Basic programing to realize the edge matching of large-scale topographic map. The basic flow of the program is data puzzle, generateing grids, edge matching, error message annotation, and finally finishing the work by man-machine interactive ways. The article also details the key technology of programming.
