    //Use Cesium World Terrain
    terrainProvider : Cesium.createWorldTerrain(),
    //Hide the base layer picker
    baseLayerPicker : false,
    //Use OpenStreetMaps
    imageryProvider : new Cesium.OpenStreetMapImageryProvider({
        url : 'https://a.tile.openstreetmap.org/'
    }),
    // Use high-res stars downloaded from https://github.com/AnalyticalGraphicsInc/cesium-assets
    skyBox : new Cesium.SkyBox({
        sources : {
          positiveX : 'stars/TychoSkymapII.t3_08192x04096_80_px.jpg',
          negativeX : 'stars/TychoSkymapII.t3_08192x04096_80_mx.jpg',
          positiveY : 'stars/TychoSkymapII.t3_08192x04096_80_py.jpg',

        }
    }),
    // Show Columbus View map with Web Mercator projection
    mapProjection : new Cesium.WebMercatorProjection()
});

//Add basic drag and drop functionality
viewer.extend(Cesium.viewerDragDropMixin);

//Show a pop-up alert if we encounter an error when processing a dropped file
viewer.dropError.addEventListener(function(dropHandler, name, error) {
    console.log(error);
    window.alert(error);
});
