Practical example on how to obtain a terrain profile from a topographic plan. Script: 1) Choose a cutting alignment of interest; 2) marks the intersections between the cut and the contour lines; 3) with the help of leader lines, we pull the marked intersection points to the respective level; 4) we connect the dots and thus obtain the terrain profile. Note1.: Please leave your feedback in the comments so that we can improve the videos even more. Note2.: If you find any incorrect information, such as a calculation error, please let us know in the comments so that it can be rectified. Sincerely, Prof. Karon Nobre
