The latest version of Google Earth added a layer for geotagged YouTube videos. So far, it seems like a lot of people are using this feature for documenting landmarks, attractions and live recordings of things like music, sporting events, backpacking trips, urban skateboarding, etc.
If you have a geospatially relevant video that you want to put on the map, it’s pretty easy. Just upload your video to YouTube, open the “Date and Map Options” tab in the video information panel, and drag the marker to the correct location. You can zoom in to get a more precise location, or just enter the lat/lon manually with the following format: “geo:lat=yy.yyyy geo:lon=xx.xxxx”.
