Hi all.

I want to change the basemap after initialization, and don’t use the default baselayerpicker.

1. var imgp1 = new Cesium.ArcGisMapServerImageryProvider( {
2. 

```
url : 'http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer'  

```

3. });
4. var imgp2 = new Cesium.TileMapServiceImageryProvider( {
5. 

```
url : '//cesiumjs.org/tilesets/imagery/blackmarble'

```

6. });
7. 
8. var viewer = new Cesium.Viewer( ‘cesiumContainer’, {
9. 

```
imageryProvider : imgp1,

```

10. 

```
baseLayerPicker : false  

```

11. });

how to switch them by myself baselayer control.

thanks.
