| 摘要基于Visual Basic6.0的集成开发环境在测量工作中具有十分重要意义，是测绘专业人员必须通晓的一门实用、有效的专业技能。对于测绘工作者来说，数据的后期处理是最重要的一个步骤，但是时代的发展渐渐淘汰了手工进行数据计算的方法，开始使用了计算机编程来解决问题。它综合性很强，涉及面不仅仅包括大地测量学、摄影测量、控制测量学等测量专业内容，还涉及数组与过程、数据结构、编程技术等多方面内容。编写的程序在测量作业和后期计算中起到了很大的作用，简化了计算，节约了时间，提高了工作效率而且还能够保证计算结果准确可靠。 本论文主要先介绍测量程序设计的出发点、重要性、过程，接着叙述测量程序设计的基础，它是有关VB6.0的简介、优越性以及批量数据的处理和常用基本程序汇编，然后介绍附和导线的简介、方法和步骤，最后着重描述附和导线在VB测量程序中的实现。40553 毕业论文关键词： VB 测量平差 导线测量 测绘 Abstract Based on VB6.0 by use of the integrated development environment has important significance to the measurement, surveying and mapping professionals must be familiar with is a practical and effective professional skills. For surveying and mapping workers, data post-processing is one of the most important steps, but the development of The Times gradually eliminated the manual data calculation method, began to use computer programming to solve the problem. It is a comprehensive strong, involve not only include geodesy, photogrammetry, control surveying, such as measuring professional content, involving arrays and process, data structure, programming, technical aspects of content. Programs written in survey work and later played a large role in calculation, simplifies the calculation, save time, improve work efficiency but also can ensure the calculation results are accurate and reliable. The starting point of this thesis mainly introduces measurement program design first, importance, process, and then related measurement program design basis, it's about VB6.0 by use of the introduction, advantages, and mass data processing and common basic programming, then introduce echo introduction, methods and steps of the wire, finally emphatically describes echo conductor in VB program implementation of measurement.
