后方交会解析点是作图根点,导線測量号三角網的联系点,和小比例尺測图的四等点的方法之一。它只要在已佈有控制網的适当地区,將仪器放在选定的未知点上,向几个已知点視測方向或角度,就可根据所測的方向或角度和有关的几个已知点的座标,标出該点的座标来。苏联测量方面認为这是一种联系控制点到主網最方便的方法。因此,他們在开始作地形測图之前,用后方交会測定解析点,將佔全部控制点的75％,可見,他們是如何的广泛采用。虽然我們
The rear intersection resolution point is one of the methods for mapping the root point, the contact point of the wire measurement triangle network, and the quadrant point of the small-scale mapping. As long as it has been placed in the control network of the appropriate area, the instrument on the selected unknown point, to several known points to detect the direction or angle, according to the measured direction or angle and the number of related The coordinates of the point, marked the coordinates of the point. The Soviet Union considered it as the most convenient way to link control points to the main network. Therefore, before they began to make topographic maps, they measured the resolution points with the rear intersection, which would account for 75% of the total control points. Therefore, they are widely used. Although we
