测量基本计算软件包设计
在测量学习和工作中，一些工作是经常需要完成的，例如坐标正反算、分幅编号、距离方位角计算、角度弧度相互转换等。一些工作如果使用人工或计算机进行运算，会有很大的缺点，不仅费时费力而且很容易出错。有的工则作必须使用计算机编程。但如果在VB程序中，将被用于测量和计算的过程如坐标正反算、分幅编号、距离方位角计算等汇聚在一起，制作成测量软件包，一些问题将迎刃而解，并将给测量工作带来很大的便利。

Abstract In recent years, surveying and mapping industry has entered the digital surveying and mapping of the progressive era, digital information data has become mapping, land, water conservancy, deformation monitoring and so on industry essential important support.Especially in the urban construction, the demand for efficient and fast digital surveying and mapping results products continued to increase and is accompanied by some engineering surveying and mapping work short construction period, high quality requirements. Now has a higher demand for digital surveying and mapping, the high standard, high quality and high speed requirements are far from some routine before the inspection data processing means to meet. This has become a big bottleneck of current production process of Surveying and mapping industry. Therefore, improve the inspection data processing means has become a urgent problem to be solved.
In the study and work measurement, some work is often needed to be done, such as coordinates of the positive and negative balance and amplitude calculation of number, range, azimuth angle and angle radian converted to each other. Some work if you use manual or computer operations, will have a lot of shortcomings, not only time-consuming and very easy to make mistakes. Some workers have to use computer programming. But if in VB program, will be used to measurement and calculation process such as the coordinates of the positive and negative, framing number, range, azimuth angle calculation together, made into a measuring software package, some problems will be solved, bring great convenience and to measure the work.
