基于Delphi 7.0和MapObjects 2.3编写控制点管理系统

对于基础测绘而言,控制点的重要性不言而喻。随着测绘范围的逐年加大,积累起来的控制点越来越多,这就要求我们要改变已有的管理方式,寻求一种新的管理方式。基于此,本文对快捷方便地管理控制点进行了研究,采用Delphi 7.0和MapObjects 2.3进行开发,较好完成了对控制点的查询、添加、删除等操作,使得图形与数据的结合,能直观地显示在"屏"上,达到了管理控制点的目的。

The Control Point Executive Program Based on Delphi 7.0 and MapObjects 2.3

For the basic surveying and mapping,the importance of control point is self-evident.As the scope of surveying and mapping enlarged year by year,the accumulated control point is more and more,this requires us to change the existing management methods and seek a new management mode.Based on this,the article was studied on how to manage the control point fast and conveniently,using Delphi 7.0 and mapobjects 2.3 procedures for the development,better to complete query,add,delete and other operations to the control point.With the combination of graphics and data,intuitive displayed in the ＂screen＂,reached management control point for the purpose.
