shortestPath

描述

¥Description

返回从 startend 的最短 path,且不与任何 特性 或障碍物 FeatureCollection<多边形> 发生碰撞。

¥Returns the shortest path from start to end without colliding with any Feature in obstacles FeatureCollection<Polygon>

参数

¥Parameters

名称类型描述
start坐标系point
end坐标系point
options?对象可选参数(默认值:
options.obstacles?多边形 | 特性<多边形> | FeatureCollection<多边形>路径无法通行的区域
options.units?单位表示分辨率和最小距离的单位;支持所有有效的 Turf 单位。(默认 'kilometers')
options.resolution?number用于计算路径的矩阵点之间的距离(默认 100)

返回

¥Returns

特性<LineString> 起点和终点之间的最短路径

¥Feature<LineString> shortest path between start and end

示例

¥Examples

var start = [-5, -6];
var end = [9, -6];
var options = {
obstacles: turf.polygon([
[
[0, -7],
[5, -7],
[5, -3],
[0, -3],
[0, -7],
],
]).geometry,
};

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