Street View in Google Maps provides 360 degree panoramic street-level views in many regions throughout the world. Google has a Street View partner program; which’s currently limited to properties that’re interesting to Google's users "Do you manage a unique property (pedestrian mall, amusement park, university campus, etc.) that users would like to visit in Street View? Through our Partner Program, you can now request Google to collect imagery of your location. Once the images are added to Street View, people all over the world will be able to virtually explore your property."
