indiff\u00e9rent que vous s\u00e9lectionnez ABSOLU ou Relatif au terrain. Dans le premier cas les valeurs de Z des g\u00e9om\u00e9tries seront utilis\u00e9es et la hauteur du terrain sera ignor\u00e9e. Dans le deuxi\u00e8me les valeurs de Z pr\u00e9sentes dans les g\u00e9om\u00e9tries seront ajout\u00e9es \u00e0 la hauteur du terrain, qui, pour ce projet est de 0m. dans les deux cas on obtient la m\u00eame valeur.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Par contre dans QField, nous avons une hauteur de terrain qui n&rsquo;est jamais 0, puisque QField utilise par d\u00e9faut MAPZEN. Il faut donc utiliser le param\u00e8tre ABSOLU pour que la hauteur soit celle des g\u00e9om\u00e9tries. Dans le cas contraire, la hauteur sera la somme de la valeur Z et de la hauteur du point dans MAPZEN.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Le d\u00e9calage doit rester \u00e0 0 car ce sera notre couche de r\u00e9f\u00e9rence pour le profil et un d\u00e9calage n&rsquo;aurait pas de sens.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2- Les couches vecteur 3D autres que le
