To get your Google Virtual Tour published, you will need to work with a local Trusted Photographer.
Street View Trusted Photographers are trained to take a series of high-quality panoramic photographs that are then “stitched” into 360-degree views using special software. These Trusted Photographers are independent contractors who have been trained and certified by Google to produce high quality panoramic images.
