Google Virtual Tours now supports multiple floors:
Do you have a business in a building of merchants on multiple floors? In the past, that has been a jumble of blue clusters, stacked one upon the other on Google Maps. The Google browser can now differentiate the tour floor levels with the proper tag meta data. It shows a stack of floor levels on the lower right side of the screen. Some call this the elevator icon.
This short video shows how I was able to cut through the blue-bubble maze, and simplify the navigation of this 4 story office building in West Nashville. Best of all, there is no additional charge for this feature with my Certified Google Business View tours.
If you have a virtual tour older than 2 years, it probably does not have this feature.
NOTE: to get the motion going up, place each photosphere on top of the other. You will see this in the 3rd to 4th floor transition on this video. I shot the others slightly apart from each other, so they seem to move sideways going up.
In addition to floor level segmentation, I can also integrate large multilevel floor plans as well.
