C'est quoi l'équidistance d'une carte ? Explication et exercices (par Mme Ruault-Djerrab)

In addition to explaining the concept of 'contour interval', I also explain what a contour line is and the different types of contour lines. I also added application exercises with map extracts to see how one can determine the contour interval, calculate the difference in altitude between two points or even the height of a cliff. Video intended for L1 students, SNV speciality (but may be convenient for another public). Video highlights: 0:08: Contour lines - definition. 2:00: Contour interval - definition and examples. 3:38: How to use contour interval - examples.
