How to Create a Radius Ring in Google Earth


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 neighborhood 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.

Things You'll Need

  • Google Earth
  • Radius drawing utility
  • Enter the latitude and longitude of the center point of your radius in a drawing utility. Some utilities are free stand-alone programs, while others are websites that will generate the radius ring for you.

  • Enter the length of the radius you wish to have extending from your center point.

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

  • Open Google Earth.

  • Open the KML file. Your radius ring has been drawn around the specified center point.
