Polygones élémentaires

Fonctions de polygone

À partir d’un ensemble de points donné, vous pouvez créer des polygones simples et calculer des quantités géométriques de base comme l’aire. Pour créer des polygones plus complexes ou accéder à des informations géométriques supplémentaires, créez un objet polyshape. Utilisez ensuite les fonctions d’objet pour modifier, faire des requêtes et visualiser le polygone ou l’ensemble de polygones.
