## README

参数1：测区多边形点集（经纬度）

参数2：外扩基线数

参数3：基线长度，单位：米（m）

参数4：航线间隔，单位：米（m）

直接初始化WaypointSpatial类，通过上述4参数执行SetWaypointSpatial、GetGMapEnvelopePolygon方法，之后即可通过GetAirlinePoints方法取得航点和航线结果。

例如：

```
let pts1 = new PointLatLng(120.314450425714,31.6047695953633);
let pts2 = new PointLatLng(120.313917403098,31.6052235856383);
let pts3 = new PointLatLng(120.312704627313,31.6044023706031);
let pts4 = new PointLatLng(120.312974182165,31.6040449919163);
				
let pts = [pts1,pts2,pts3,pts4]; //测区多边形
//let angel = 45;
let BASELINENUMBER = 3;  //外扩基线数量
let PortraitOverlap = 21; //基线长度，m
let SideOverlap = 26; //航线间隔，m
				
let wp = new WaypointSpatial();
wp.SetWaypointSpatial(pts, angel, BASELINENUMBER * PortraitOverlap);//默认外扩N个基线长度
wp.GetGMapEnvelopePolygon();//计算外包矩形
				
//计算航线点和航线
let airlinepts = wp.GetAirlinePoints(SideOverlap);
```
