Google 地图和 Turf.js 折线集成

Question

我正在研究 google 地图和 turf js 集成示例。我添加了带有 GeoJson data.Working 片段的行。但我想从草皮线位置创建一条多段线。

for (var j = 0; j < line.geometry.coordinates.length; j++) {
    var wp = new google.maps.LatLng(line.geometry.coordinates[j][1], line.geometry.coordinates[j][0])
    path.push(wp);
}

我尝试创建一条路径，然后根据这条路径创建我的多段线，但无法从草皮线阵列中创建一条路径。

我该怎么做？

提前致谢！

var path = [];
  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 2,
    maxZoom: 8,
    minZoom: 1,
    center: {
      lat: 0,
      lng: -180
    },
    streetViewControl: false,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  });

var line = {
    "type": "Feature",
    "properties": { "line": "on" },
    "geometry": {
      "type": "LineString",
      "coordinates": [
        [-122.214, 37.772],
    [-157.821, 21.291],
    [178.431, -18.142],
    [153.027, -27.467]
      ]
    }
  };
     map.data.addGeoJson(line);
     
     
     
    var point = turf.point([185.431, -4.542]);

  var marker = new google.maps.Marker({
    position: new google.maps.LatLng(point.geometry.coordinates[1], point.geometry.coordinates[0]),
    map: map,
  });

html,
body,
#map {
  height: 100%;
  width: 100%;
  padding: 0px;
  margin: 0px;
}

<script src="https://maps.googleapis.com/maps/api/js"></script>
<script src="https://npmcdn.com/@turf/turf@4.7.2/turf.min.js"></script>
<div id="map"></div>

Answer 1

您需要创建折线并将其添加到地图中：

var polyline = new google.maps.Polyline({
    path: path
});

polyline.setMap(map);

Answer 2

我解决了，就是没看到...

$.each(line.geometry.coordinates, function (key) {
    var wp = { lat: line.geometry.coordinates[key][1], lng: line.geometry.coordinates[key][0] }
    path.push(wp);
});
