        <gco:CharacterString>Base de données de l'occupation du sol du Grand Est (OCS Grand Est) sur le département de la Marne (51). La nomenclature est composée de 4 niveaux emboités de 53 postes décrivant le couvert, un niveau 5 transversal caractérise la perméabilité du sol des zones artificialisées. La publication du 3e millésime introduit les éléments suivants :

- Un niveau 6 associé aux emprises militaires. 
- Une correspondance avec la nomenclature de l’OCSGE IGN et les classes caractérisant le couvert
- Une correspondance avec la nomenclature de la loi LCR en 10 classes relative au Décret no 2023-1096 du 27 novembre 2023 relatif à l’évaluation et au suivi de l’artificialisation des sols [Plus d'information](https://www.legifrance.gouv.fr/download/file/3yIijoSN0rfmEsh7Tl3hScKaN5YM8TCPy2C_ZbLX96A=/JOE_TEXTE)

Les fichiers de données sont accessibles en téléchargement via ce [lien](https://ftp.datagrandest.fr/opendata/ocs-grand-est/51/).
Les données sont accompagnées d'une documentation, de projets QGIS et ArcMap et de leurs fichiers de style prêts à l'emploi.</gco:CharacterString>
