ArcGIS JS 4加载第三方矢量切片

        现在矢量切片越来越普及,对于地图渲染能更轻更快。ArcGIS JS 4.13可以实现加载第三方矢量切片,以下为代码示例,最下方是我之前切的建筑物数据。

        当切片大小在1M左右,加载效果还是可以。不过跟mapbox gl相比还是有些逊色,mapbox gl可以加载6M大小的切片,但ArcGIS JS 4却不行。矢量切片还是需要控制好大小,这样才能快速传输和渲染。

      "version": 8,
      "sources": {
       "osm": {
         "tiles": ["https://osm-lambda.tegola.io/v1/maps/osm/{z}/{x}/{y}.pbf"],
          "type": "vector"
        }
      },
      "layers": [
       {
         id: "land",
          type: "fill",
          source: "osm",
          "source-layer": "land",
          minzoom: 0,
          maxzoom: 24,
          paint: {
           "fill-color": "rgba(150, 150, 150, 1)"
         }
       }
      ],
      "id": "test"
    }
    
    require([
     "esri/Map",
     "esri/views/MapView",
     "esri/layers/VectorTileLayer",
     "dojo/domReady!"
    ], function(Map, MapView, VectorTileLayer) {
     var map = new Map();
      var view = new MapView({
       container: "map",
        map: map,
        center: [-98.5795, 39.8283],
       zoom: 2,
     });
      var tileLyr = new VectorTileLayer({
       style: style
      });
      map.add(tileLyr);
    });
