var viewer = new Cesium.Viewer("cesiumContainer");
var imageryProviderViewModels = viewer.baseLayerPicker.viewModel.imageryProviderViewModels;
viewer.baseLayerPicker.viewModel.selectedImagery = imageryProviderViewModels[imageryProviderViewModels.length - 1];
viewer.scene.debugShowFramesPerSecond = true;
var provinceLayer = null;
var provinceProvider = new VectorTileImageryProvider({

simplify: false
});
provinceProvider.readyPromise.then(function () {
provinceLayer = viewer.imageryLayers.addImageryProvider(provinceProvider);
});
var worldLayer = null;
var worldProvider = new VectorTileImageryProvider({
