* Surveys (I had the county come in once in my sort-of legal rental appartment when they were legalising them, they needed to make a floor plan and fire safety recommendations)

* Video games. Very generic usage.
* Virtualised museums, but those would likely need extra work to make all the placards etc readable
* Street View next level, also indoor navigation.
