shortestPath

Returns the shortest path from start to end without colliding with any Feature in obstacles
返回从头到尾的最短路径，而不与障碍物中的任何Feature发生碰撞

参数

参数	类型	描述
start	Coord	point
end	Coord	point
options	Object	可选参数：见下文

options选项

属性	类型	默认值	描述
obstacles	Geometry|Feature|FeatureCollection <Polygon>)		areas which path cannot travel
minDistance	(number)		minimum distance between shortest path and obstacles
units	string	kilometers	unit in which resolution & minimum distance will be expressed in; it can be degrees, radians, miles, kilometers, ...
resolution	number	100	distance between matrix points on which the path will be calculateds

返回

Feature <LineString> - shortest path between start and end

示例

var start = [-5, -6];
var end = [9, -6];
var options = {
  obstacles: turf.polygon([[[0, -7], [5, -7], [5, -3], [0, -3], [0, -7]]]) // 注意：polygon首尾坐标要一致
};

var path = turf.shortestPath(start, end, options);
