20 Topography & Contours Contour Lines identify the ground elevation. Contour Lines identify the ground elevation. All points along a single contour line have the same elevation.All points along a single contour line have the same elevation. The interval between contours can represent any convenient distance. (i.e. 1’, 2’, 5’, etc…)The interval between contours can represent any convenient distance. (i.e. 1’, 2’, 5’, etc…) Topography is the location and elevation of features, consisting of both natural and man-made objects. Topography is the location and elevation of features, consisting of both natural and man-made objects.

22 Cross Sections Cross sections show the “inside” of a structure, or the elevations of the earth and structures along a station. Cross sections show the “inside” of a structure, or the elevations of the earth and structures along a station. Used heavily in earthworks and highway construction. Used heavily in earthworks and highway construction. Provided for features whose construction is not shown clearly on plan or elevation drawings. Provided for features whose construction is not shown clearly on plan or elevation drawings.

23 Example of Cross Section

24 Profiles Profiles are vertical sections through a topographic map that shows the earth’s surface at any location along an alignment. Profiles are vertical sections through a topographic map that shows the earth’s surface at any location along an alignment. Profiles often have a vertical exaggeration in order to show more detail of the surface. Profiles often have a vertical exaggeration in order to show more detail of the surface.
