Google Maps is a free, web-based program that allows registered users to explore and annotate maps. There are three drawing tools used for editing maps: "Draw A Line," "Draw Along Roads," Draw A Shape." These tools can be used to outline counties, map driving directions or highlight regions. Once they are personalised, you can share maps in a variety of ways. Print maps for hard-copy displays. E-mail interactive maps to friends. Or change your sharing permissions and make the project available for group collaboration.
Open "Google Maps."
Click the "Sign In" button in the upper-right hand corner of the screen. Enter your e-mail address and password.
Click "My Maps" at the top of the left navigation menu.
Hover over the name of a map and click the left mouse button. Click "Edit" in the upper-right corner of the left navigation menu. Center the map over the county to be outlined.
Find the drawing tool menu at the top of the map window; it is the last button in the row of three buttons. The icon on the drawing button is shaped like an "N." Click the small blue arrow next to the icon to open the menu. Select "Draw A Line" from the drop-down menu.
Place the pointer, shaped like a cross hair, over the border of the county. Left click to place a mark and begin drawing a line. Move the cross hair further along the border of the county and left click again. Continue until the county is outlined. Click on the last point to close the shape.
Enter a description of the outline.
Use "Draw A Shape" instead of "Draw A Line" if you want to highlight the county with a colour. The procedure is the same. If you need a hand finding county borders, check the U.S. Census database for maps.
