Google Earth is a powerful online map-making application. It merges satellite data with map images and, in some areas, even street views for a realistic and informative tour of the globe. With Google Earth, you can explore your neighbourhood or the world from your computer and plan trips; however, it lacks the ability to draw a circle with a specified radius around a point. To do this, you must use a third-party program or website to create a Keyhole Markup Language (KML) file for use within Google Earth. KML files involve an implementation of Extensible Markup Language, or XML, to import geographic data into Google Earth.

  3. 3

    Generate the KML file. If you're using a website, download the KML file to your computer.
