What is a Topographic Map?
represent lines of equal elevation above (or below) a reference datum. To visualize what a contour line represents, picture a mountain (or any other topographic feature) and imagine slicing through it with a perfectly flat, horizontal piece of glass. The intersection of the moun...
Science Junction: Which way is North?
topographic map is a representation of a three-dimensional surface on a flat piece of paper. Contour lines, sometimes called "level lines," join points of equal elevation. The closer together the contour lines appear on a topographic map, the steeper the slope (...
Types of Maps
maps to plan trips and for driving directions. Topographic maps include contour lines to show the shape and elevation of an area. Lines that are close together indicate steep terrain, and lines that are far apart indicate flat terrain. Fact Monster/Information Pl...
Mapping Potato Island
If you were taking a hike along a hillside and not walking either uphill or downhill, you would be walking on a contour line. When contour lines are close together, the slope is very steep. When contour lines are far apart, the slope is very shallow. This type of map is h...
