測角图根点虽然是較低級的控制点,一般技术要求不高,但由于它数量較多,在控制測量的总工作量中佔有相当的比重。因此採用什么样的佈设方式能够做到既省工又合乎精度要求,一直是值得研究和討論的問题。最近由于領导上的大力支持,我們得在某地区尝試地运用了一种較比不同的佈设方法——內分点佈設法,即在四等三角点下佈设內分点,再在內分点间敷設測圖用的附合鎖。經实踐証明:在一定的条件下,它还是可用的,能够提高效率,滿足要求。茲拟就这一方法的原理和我們实踐所得作一介紹。由于技
Although the root point of the goniogram is a lower-level control point, the general technical requirement is not high, but due to its large number, it occupies a considerable proportion of the total workload of the control measurement. Therefore, it is always worth to study and discuss the issue of what kind of layout method can be used to save both work and accuracy requirements. Recently, due to the strong support from the leaders, we have tried to apply a rather different layout method in a certain area - the inner point distribution method, that is, setting the inner division point under the fourth triangle point Laying the map with the lock between the points. Practice has proved that: under certain conditions, it is still available, can improve efficiency and meet the requirements. We intend to introduce the principle of this method and our practice.
