Google

Layer for using Google Maps data within OpenLayers. For API information, see the Google Layer API Docs. For an example of usage, see the Spherical Mercator example.
If you are overlaying other data on a Google Maps base layer, you will want to be interacting with the Google Maps layer in projected coordinates. (This is important if you are working with imagery data especially.) You can read more about the ‘Spherical Mercator’ projection that Google Maps – and other commercial layers – use in the Spherical Mercator documentation.
The Google Layer class is designed to be used only as a base layer.
