Cross-Sections

 * 1) Place the straight edge of a piece of paper along the points (A to B).
 * 2) Starting from the first point (point A), mark the position where the edge of your piece of paper cuts each contour line and write the value of that countour line.
 * 3) Draw the horizontal and vertical axes for your cross-section (the length for your cross-section should match the distance from A-B.
 * 4) Place your paper along the horizontal axis and plot the contour points and heights according to the scale on the cross-section.
 * 5) Join the dots with a single, smooth curved line to show the slope of the hill (relief).
 * 6) Label any features that you have included in your cross-section such as rivers using a key.
