A lot of cameras and smartphones images record EXIF GPS LAT/Long and Pano2VR uses those type of coordinates with Google Map Services.
That would be 2.75" /year x 10 years = 27.5" or over 30cm. All your map panoramas are required to be reshot or updated for accuracy.

"Australia drifts away from GNSS measurements. Australia is moving north at the rate of approximately 2.75 inches per year, causing it to be out of sync with GNSS positioning by nearly five feet. Scientists are working to correct the measurement problems."
Only the Gnomes would know this.
