Crowd sourced surveyors

Suppose you live in Bangkok and you need to go visit a building site in Nakhon Si Thammarat.
You could either fly or drive there or employ a local to take a few pictures for you.

Or someone tells you about this place which is for sale.
You could either spend 20 minutes for a drive there or you could employ someone to take pictures for you e.g. 3 sets of pictures: morning, evening and night. Anyone with a camera and internet connection can do this.

It's similar to a mechanical turk but geographically diverse.

Better still, a robot with:

1. cameras to replace your eyes
2. internet connection - to transmit images
3. GPS receiver & transmitter in case it gets lost
4. simple translator that says

Create a business to do this: online surveying.
