Embodiment 1
[0043] Embodiment 1: The lowest level is the case of a non-level 1 link.
[0044] In the first step, the site control range l is given;
[0045] In the second step, the length L of each link is divided by the control range l and rounded to obtain the level of each link, such as figure 1 Shown can be cut with a circle of radius l, in the appendix figure 1 Among them, the lengths of the 6 links are divided by 1, and 3 2-level links, 2 3-level links, and 1 6-level link are obtained;
[0046] The third step is to discretize the links according to the classification results, divide the links equally according to the link level, and take the center point of each segment link after equal division as the virtual rainfall station, as shown in figure 1 As shown, the level 3 link is divided into 3 equal parts, and the focus of the segment is the virtual site;
[0047] The fourth step is to determine the initial site location and valuation. Since there is no level 1 link, the middle p...
Embodiment 2
[0063] Embodiment 2: The lowest level is a level 1 link situation.
[0064] If there are level 1 links that meet the quantity requirements, then:
[0065] In the first step, the site control range l is given;
[0066] In the second step, the length L of each link is divided by the control range l and rounded to obtain the level of each link;
[0067] The third step is to discretize the links according to the classification results, divide the links equally according to the link level, and take the center point of each segment link after equal division as the virtual rainfall station;
[0068] The fourth step is to determine the initial site location and valuation. Since the lowest level is level 1, the center points of all level 1 links are taken as the initial site location, the aggregated data of each link line at this level is the definite site estimate, and the value of the initial site is the final estimate of the level site;
[0069] The fifth step is the preliminary ...
