OpenStreetMapLayer

[Wade]

Using the OSM layer, is it possible to customize SpatialReference ?

[jcarlson]

Can you clarify what you're referring to when you say "OSM layer"? Do you mean the feature services? Or the vector tile basemap service?

the vector tile basemap service 

      require(["esri/layers/OpenStreetMapLayer", "esri/Map", "esri/views/SceneView"], (
        OpenStreetMapLayer,
        Map,
        SceneView
      ) => {
        const map = new Map({
          ground: "world-elevation"
        });

        const view = new SceneView({
          map: map,
          container: "viewDiv"
        });

        const osmLayer = new OpenStreetMapLayer();
        map.add(osmLayer);
      });
