The Coastal Zones (CZ) LC/LU product for 2012 is providing a detailed Land Cover / Land Use (LC/ LU) dataset for areas along the coastline of the EEA38 countries and the United Kingdom, with reference year 2012 for the classification. This product monitors landscape dynamics in European coastal territory to an inland depth of 10 km with a total area of approximately 730,000 km², with all the relevant areas (estuaries, coastal lowlands, nature reserves). The production of the coastal zone layers was coordinated by the European Environment Agency (EEA) in the frame of the EU Copernicus programme, as part of the Copernicus Land Monitoring Service (CLMS) Local Component. The Coastal Zones product covers a buffer zone of coastline derived from EU-Hydro v1.1. Land Cover/Land Use (LC/LU) layer is extracted from Very High Resolution (VHR) satellite data and other available data. The class definitions follow the pre-defined nomenclature on the basis of Mapping and Assessment of Ecosystems and their Services (MAES) typology of ecosystems (Level 1 to Level 4) and CORINE Land Cover adapted to the specific characteristics of coastal zones. The classification provides 71 distinct thematic classes with a Minimum Mapping Unit (MMU) of 0.5 ha and a Minimum Mapping Width (MMW) of 10 m. The product is available for the 2012 and 2018 reference year including change mapping. This CZ dataset is distributed in vector format, in a single OGC GeoPackage SQLite file covering the area of interest.

The Coastal Zones (CZ) LC/LU product for 2018 is providing a detailed Land Cover / Land Use (LC/ LU) dataset for areas along the coastline of the EEA38 countries and the United Kingdom, with reference year 2018 for the classification. This product monitors landscape dynamics in European coastal territory to an inland depth of 10 km with a total area of approximately 730,000 km², with all the relevant areas (estuaries, coastal lowlands, nature reserves).

The Coastal Zones LC/LU Change (CZC) 2012-2018 is providing the Land Cover / Land Use (LC/ LU) change for areas along the coastline of the EEA38 countries and the United Kingdom, between the reference years 2012 and 2018. The Coastal Zones product monitors landscape dynamics in European coastal territory to an inland depth of 10 km with a total area of approximately 730,000 km², with all the relevant areas (estuaries, coastal lowlands, nature reserves). The production of the coastal zone layers was coordinated by the European Environment Agency (EEA) in the frame of the EU Copernicus programme, as part of the Copernicus Land Monitoring Service (CLMS) Local Component. The Coastal Zones Change product covers a buffer zone of coastline derived from EU-Hydro v1.1. The Land Cover/Land Use (LC/LU) Change layer is extracted from Very High Resolution (VHR) satellite data and other available data. The reference years for the change are 2012 and 2018. The class definitions follow the pre-defined nomenclature on the basis of Mapping and Assessment of Ecosystems and their Services (MAES) typology of ecosystems (Level 1 to Level 4) and CORINE Land Cover adapted to the specific characteristics of coastal zones. The classification provides 71 distinct thematic classes with a Minimum Mapping Unit (MMU) of 0.5 ha and a Minimum Mapping Width (MMW) of 10 m. The status product is available for the 2012 and 2018 reference years. This CZC dataset is distributed in vector format, in a single OGC GeoPackage file covering the area of interest.

Bornage du réseau routier départemental constitué de PR (point routier) présents physiquement sur le terrain (bornes, plaquettes, etc.). Ils sont dénommés PLO (point de localisation) dans le système d'information géographique. Ils permettent de se repérer de manière précise sur le graphe et servent à définir la localisation des informations sur les routes départementales. Trois types de PLO sont définis : D : Point de localisation de début d'axe PR : Point repère ou borne F : Point de localisation de fin d'axe

Hiérarchisation du réseau routier départemental en fonction des caractéristiques de chaque section de route et de son usage. Le réseau routier est classé en quatre catégories. 1 Grandes liaisons 2 Réseau structurant 3 Réseau secondaire 4 Réseau d'intérêt communal

La signature isotopique et biochimique des différents producteurs primaires du Bassin d'Arcachon et de son bassin versant est analysée. Les producteurs primaires ont été prélevés sur les 19 stations intertidales considérées dans la fiche de métadonnées:"Cartographie de la matière organique particulaire benthique dans le Bassin d'Arcachon".

Les consommateurs primaires de la macrofaune benthique ont été prélevés à trois saisons (avril, septembre 2009 et février 2010) et sur les 31 stations benthiques considérées dans la fiche "Cartographie de la matière organique particulaire benthique dans le Bassin d'Arcachon". Le zooplancton a été prélevé aux mêmes dates sur les 4 stations pélagiques de suivi interne au bassin. Des analyses isotopiques et biochimiques sont réalisées sur ces consommateurs primaires.

Position géographique des points de mesure du service des réseaux "Pluviaux" de la Communauté d'Agglomération de La Rochelle au débouché en mer des pluviaux primaires et indicateurs de qualité établis à partir des mesures de 2005 à 2008

31 stations font l'objet d'échantillonnage benthique en zone subtidale et intertidale selon un gradient de présence d'herbier à zostera noltii. Les cartes sont réalisées en avril et en septembre.
