Within this concentric shape, draw a still smaller version of the island's shape, this time between the points where the 200' lines cross the baseline. Now you have a representation of the sea-level, 100', and 200' elevations of your island using the shape of your contour lines. Contour lines are one of many symbols you can show on your island. Erase the light parallel lines you drew to help you create the island's contours accurately. With this wonderful start on your island, create and use other symbols.
Areas are features such as forests.
Lines are features like roads or rivers-with beginning and end points. And points are features such as dots that can look like squares to represent houses. Use symbols to show real objects and places-like little pictures. You can also use lots of colors to make interesting symbols. Add each symbol you use to your legend.
