Roman Nurik is a Googler who develops tools to help developers create Google Earth applications. Recently he announced on Twitter the release of an application he’s developed using the GE API which lets you easily pass a URL as a placemark. An app like this is handy for twitter which is all about passing short URLs to help add context to a message. Roman calls the app EarthURL.org. You simply use the GE Plugin to fly to a place you want to share, position the view you want (including 3D view angle), and then copy and paste the URL. Here, for example, is the Sphynx in Egypt .
EarthURL isn’t the first easy GE URL targeted for Twitter (see EarthTwit), and going way back to shortly after Google Earth was released in 2005 there was the introduction of Tagzania. Tagzania allows you to mark placemarks in a concept they call “tags”, and their URLs are short and easy to understand. See for example the location of the Eiffel Tower on their site, or with Google Earth . Tagzania also lets you embed their tagged locations on a web page.
