How many panoramas are needed to cover my business interior?
The maximum of panoramic nodes per business allowed by Google is 500. The red dots near the entrance area of the sample floor plans are mandatory shots in front and immediately inside of a business. The panoramic shots should be approximately 15 feet apart from each other. Roughly you will need one Panorama per 150 square feet. There must be also one panorama immediately before and after every doorway .
Apply these rules to your own floor plan and you should be able to calculate the number of panoramas needed to cover your space.
