Since time ago, I added semantic web tags to my photo album, hoping they'd then appear on the public map. They already have location data in EXIF tags.
Nothing happened. I don't know of any site that indexes images in this way.
That is I would take some pictures on my Android 5.1 phone and Google Maps would pop a notification. Not sure when it started but this kind of camera/Google Maps "integration" was not present in 4.4.
The places of interest that Google detects are generally correct but I have zero interest in adding personal pictures to their public/private DB.
I keep declining but my anger grows.
