Google is now letting its users geographically tie YouTube videos to specific places on Google Earth, the company’s satellite imagery mapping service. A new YouTube video layer has been added to Google Earth, which allows Google Earth users to see videos of places they select. More information can be found at this link.

This is an example of ”geotagging," which means giving data geospatial attributes. Yahoo’s popular photo site, Flickr, allows geotagging of photos, so that user-uploaded photos can be tied to geographical points on a map. Nearly 30 million photos on Flickr contain geospatial metadata.
