Contour lines normally connect areas with equal data values, so may generally be called isolines or isopleths-lines of the same value. Normally, the primary set of contour lines is displayed as a solid line, while the secondary contour is displayed as a &shed line. For example, a standard 850-hPa, 24-hour prognosis chart has height contours in solid lines, temperature contours in dashed lines, and wind speed and direction as plotted data.
Contour lines follow certain rules. Contour lines on topographic maps can help you visualize landforms. Think of the following statements as rules for reading such maps: â¢ Lines never cross. Contour lines never cross, because each linerepresents an exact elevation.he more gradual the slope, thefarther apart the contour lines on the map.The steeper the slope, the closer togetherthe contour lines.The of an area is the difference between its high and lowpoints. For example, subtracting the lowest elevation on the mapfrom the highest gives you a measure of the areaâs relief.
