基于ArcEngine的交会测量程序设计与实现

Design and Implementation of Intersection Survey Program Based on ArcEngine

ArcEngine的IConstructPoint2接口提供了点的绘制方法,这些方法直接或间接提供了前方交会、后方交会等交会测量的方法,将这些方法进行封装,可以进行交会测量程序设计。文章借助于IConstructPoint2接口提供的点的绘制方法,以前方交会和后方交会为例进行了交会测量程序设计与实现。实践证明:基于ArcEngine的交会测量程序具有实现简单,可视化强的优点。

the IConstructPoint2 interface of ArcEngine provides point rendering method, these methods directly or indirectly provide the intersection survey method of forward intersection and resection, one can make the design of intersection survey program by encapsula- ting these methods. By using the point drawing method provided by IConstructPoint2 interface,the paper designs and implements inter- section survey program taking forward intersection and resection as an example. Practice has proved that intersection survey program based on AreEngine is simple to implement and it has the advantage of visualization.
