With the help of these lessons, you may begin to visualize and create the elevation profile of land surfaces along a horizontal alignment.

In a profile, surface elevations are mostly displayed along a horizontal alignment.

Use profiles to see the landscape over a certain area or along a route of interest. Surface profiles, layout profiles, overlaid profiles, fast profiles, and corridor profiles are a few of the several sorts of profiles.

Crest curves and sag curves are the two types of curves used in layout profiles. Hilltops or other locations where the slope drops in value are where crest curves are put. Positive to positive grade transitions, positive to positive, and negative to negative are the three different forms of crest curves.

Sag curves are positioned in valleys or other areas where the gradient increases. A negative to positive grade transition, a negative to negative, and a positive to positive are three examples of sag curves.

You choose whether a surface profile is dynamic or static when you construct it. If the surface elevation varies, a dynamic profile automatically adjusts. If you adjust the surface or move the horizontal alignment, such changes may take place. A static profile does not adapt to changes in the surface and reflects the terrain as it was when it was first constructed.
