      <gmd:abstract>
        <gco:CharacterString>Le MNTB de 2018 a été produit à partir de données LiDAR. L'emprise de ce produit recouvre les limites du Schéma de Cohérence Territorial (SCoT) en application sur les communes faisant partie de la MEL, de la Communauté de Communes de la Haute Deûle (5 communes au sud du territoire métropolitain) et de la Communauté de Communes Pévèle Carembault (38 communes au sud-est du territoire métropolitain). De plus, cette emprise outrepasse légèrement cette limite administrative, permettant de disposer de données sur le secteur frontalier au nord-ouest et nord-est de l’actuel territoire métropolitain ainsi que les territoires limitrophes, sur 2 à 8 kms hors des limites du SCoT.

Ce type de données permet de représenter le relief du terrain et le bâti sous la forme d'une grille raster. La donnée source (LiDAR) permet de discriminer les données sol et sur-sol, et donc d'exclure les informations liées à la végétation.

**Données associés :**

* Nuage de points issu du LiDAR - SCoT Lille Metropole et MEL - 2018

* MNT (modèle numérique de terrain) issu du LiDAR - SCoT Lille Metropole et MEL - 2018 

* MNE (modèle numérique d'élévation) issu du LiDAR - SCoT Lille Metropole et MEL - 2018
