Create a custom basemap

This sample demonstrates how to create a custom basemap and add it to the BasemapToggle widget in a SceneView. The basemap is a simple container of baseLayers and reference layers.

A WebTileLayer is created from a third-party cached service and added to a new basemap's baseLayers property so it can be used as an alternate basemap.

// Create a WebTileLayer with a third-party cached service
var mapBaseLayer = new WebTileLayer({
  urlTemplate: "http://{subDomain}.tile.stamen.com/terrain/{level}/{col}/{row}.png",
  subDomains: ["a", "b", "c", "d"],
  copyright: "Map tiles by <a href=\"http://stamen.com/\">Stamen Design</a>, " +

    "Data by <a href=\"http://openstreetmap.org/\">OpenStreetMap</a>, " +
    "under <a href=\"http://creativecommons.org/licenses/by-sa/3.0\">CC BY SA</a>."
});

// Create a Basemap with the WebTileLayer. The thumbnailUrl will be used for
// the image in the BasemapToggle widget.
var stamen = new Basemap({
  baseLayers: [ mapBaseLayer ],
  title: "Terrain",
  id: "terrain",
  thumbnailUrl: "https://stamen-tiles.a.ssl.fastly.net/terrain/10/177/409.png"
});

// Add the custom basemap to the map
var map = new Map({
  basemap: stamen,
  ground: "world-elevation"
});
