Google Maps and Streetview
Imagine you have an admin area in which your client could specify several outlets, this could be a way to grab the locations and streetviews for these outlets ready to be reused later on the front end of the site. In this example, if you have made your location available through your browser, then the application will try to automatically find you. Failing this, just enter a postcode. You are then able to move the marker and also the Google Pegman to point at your location, thus initiating the Streetview. On the right you will see the information for the Marker (Location) and the Streetview position. This information could be used later for customers looking for outlets 
To start just enter a UK postcode and click search.
