围栏原始坐标系

这里描述的是围栏数组本来来自哪个坐标系。绘制前会自动换算到当前底图坐标（GCJ-02）。

围栏顶点 0 个

收货地址经纬度

收货点原始坐标系

这里描述的是下面手工输入的收货点本来来自哪个坐标系。判断前会自动换算到当前底图坐标（GCJ-02）。

也可以直接点击地图选取候选点；点击不会立刻覆盖输入框，需要确认后才会作为收货地址。

经度（lng）

纬度（lat）

当前底图：高德地图瓦片（GCJ-02）
围栏输入：使用“围栏原始坐标系”设置
收货点输入：使用“收货点原始坐标系”设置
转换规则：BD-09 会自动换算到 GCJ-02，再绘制围栏和执行判断
判定算法：射线法（Ray Casting），按底图坐标判断
