YouEarth is a plugin what allows you to search for youtube videos with GEOlocation information, and plot them on Google Earth.
Using the built-in YouTube search, you can import video details into the YouEarth database. After getting a Google Earth API key from the Google website and entering that into YouEarth, you can put a [youearth] shortcode in a post or a page and you will find a GoogleEarth instance there with your videos pinned on it.
YouEarth includes the ability to search YouTube for videos using the YouTube API, and will check each video has either GEO location coordinate data or the uploaded location before returning it. It is possible to search for videos directly using the video ID also.
