Geolocation currently means "where am I". Can this evolve to add "what I see"?  
   For example I'm standing at a location and take a picture of a Bird on a Tree using a device. My location is (x1,y1,0) and the location of Bird is (x2,y2,<relative angle,height and distance from me>). Assume the device is able to compute "<relative angle/height and distance from me>", and geotag that picture with such location.  
   Above case can be generalized for a Video geotagging too.

Subject: Standard for geotagging video with video-frame metadata

    I wanted to share a blog post requesting standard for tagging video with "device" metadata like location/device orientiation etc.  
Also to add to it, there is a need for user/web-app to access and reference (in terms of space) remote video frames.
