What you need to do — To add your very own Street View imagery to Google, you need to record a series of photos in the area you're in. You'll probably have to walk down a pedestrian pathway, for example. Once you've recorded your images, you publish them to the Street View app. After that, Google will position the imagery accordingly — depending on the need to rotate, tweak an angle, and then stitch a series of clips together for a rotational view.
Once approved, your imagery goes up on the designated location. At this moment, the beta feature is live for certain areas, including Costa Rica, Nigeria, Indonesia, New York, and Toronto. User-created photos will appear on the map with dotted blue lines. If an area already has official imagery from Google Street View, you will see a solid blue line.
How to opt out — Of course, privacy advocates and anyone with a remote sense of unease with their house imagery showing up on a public map will object to this mainstreaming of Street View photography. Anticipating criticism, Google insists that these images will be up for review and that users do have the ability to report inappropriate or potentially dangerous photos. But if you still feel uncomfortable with the notion of your private residence becoming map material, you can report an "inappropriate street view" to Google, citing a privacy or security concern. Although there's no guarantee, hopefully Google listens to your apprehensions.
