使用地理工具将FeatureCollection转换为LineString

// 引入Turf.js库
const turf = require('@turf/turf');

// 定义一个FeatureCollection
const featureCollection = {
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "geometry": {
        "type": "Point",
        "coordinates": [0, 0]
      },
      "properties": {
        "name": "Point 1"
      }
    },
    {
      "type": "Feature",
      "geometry": {
        "type": "Point",
        "coordinates": [1, 1]
      },
      "properties": {
        "name": "Point 2"
      }
    },
    {
      "type": "Feature",
      "geometry": {
        "type": "Point",
        "coordinates": [2, 2]
      },
      "properties": {
        "name": "Point 3"
      }
    }
  ]
};

// 将FeatureCollection转换为LineString
const lineString = turf.lineString(turf.coordAll(featureCollection));

// 打印转换结果
console.log(lineString);
