The My Places feature in Google Maps allows you to create your own maps and share them with other users. In addition to standard placemarks and lines, you can also outline areas in your custom map. The shapes tool in Google Maps allows you to draw an outline around an area. After you've outlined the area, the entire outlined area is shown in a different color on your map. You can make multiple outlined areas, showing the boundaries between different geographic areas on a map.
