Google Earth can make creating radius rings on a map quick and easy. The trick is using the Show Ruler tool. When you’ve finished, you can import the rings into Adobe Illustrator or into Google Maps where you can share them on a map with others.
With Google Earth Pro as a free download, mapmakers now have additional tools at hand. One tool is Google Earth Pro’s Show Ruler tool. With it you can draw radius rings and save them as .kmz files you can then import into Adobe Illustrator using Avenza’s MAPublisher plug-ins.
