我的地图有如下图所示的地点。
这些地点位于纬度/升度和 Car(x、y、z)坐标的C#Dictionary物体。 该地区由5个小组负责,其中第一个小组位于该地区西南部。 我需要的是能够确定这些要点,以便最南半球最突出的点是第一点——这是地图上Enisluen附近的绿色3标记。 我正在尝试不同的办法,但未能取得我所希望的结果。
谁能解释一种能够发挥作用的办法?

假设你知道该地图的南西角的Lt / Long,我将使用Aviation Approachry计算每一点的距离。 然后,你不得不根据所计算的距离进行分类。
如果你想要以类似于“最南端”的方式界定“最南湿”的定义,你可以按<代码>x+y排列<>。 你们可以认为,这是从整个系统角移至整个地图上的NW-SE线,同时注意到达到点数的顺序。 这相当于通过在<代码>y上进行分类来界定“最南端”的定义,在这种分类中,你重新将东西线从南边移,并指出你达到每一点的顺序。
我将使用“黑客”方案确定地图西南部的一些地点与每一点之间的距离。 这里与C#和Sql服务器的一些代码挂钩,以便做这件事。
