Google has integrated geotagged YouTube videos into Google Earth. By selecting the “YouTube” layer in the “Featured Content” section section of Google Earth, you can see the locations of YouTube videos. Clicking on the icon allows you to play the video in Google Earth.

It is a great way to learn about a place.

As with geotagged pictures, the biggest challenge is the volume and variety of content. Even with the limited amount of geotagging happening today, major cities are blanketed with videos. The white markers in the screenshot above are a fraction of the geotagged videos. As you zoom in further, more appear.

They include videos of tourist sites, personal birthday parties, concerts, subway trains going by, etc. We’ll need ways to filter the firehose of content to what we’re interested in at the moment. Google Earth already does a great job of letting you pick among data sources; I suspect that in the near future the YouTube layer will be segmented by category.
