        <gco:CharacterString>La couche des cours d'eau regroupe dans une même couche les cours d'eau considérés comme réservoirs de biodiversité et ceux considérés comme corridors écologiques. 
Le fichier cours_eau.zip contient les couches géographiques (vecteur) suivantes :
- CER_COURS_EAU_S_44.shp : Cours d'eau du territoire de la Région Grand Est, contenant l'information "est réservoir" ou "est corridor". La couche est de forme polygone pour pallier les erreurs topologiques issues des anciens SRCE. 
- CER_COURS_EAU_L_44_detail.shp : Couche de détail des cours d'eau réservoir, ayant pour vocation d'être une couche de rappel sur la donnée d'origine des réservoirs de biodiversité liés aux cours d'eau. 

Le répertoire temp_cours_eau_qml.zip contient les fichiers de styles (format QML - QGis) :
- CER_COURS_EAU_S_44_style.qml : couche de style associée à la couche CER_COURS_EAU_S_44.shp

Le fichier note_methodo.pdf contient une note méthodologique sur la manière dont les données ont été constituées ainsi que la description des champs de chacune des données.</gco:CharacterString>

            <gco:CharacterString>Certaines couches historiques (notamment des ex-SRCE) comportent des doublons et problèmes de topologie, trop importants pour être résolus. Pour remédier à cela, il a été choisi de passer la couche sous format polygone en appliquant une zone tampon de 10m autour du linéaire de cours d’eau. Par un traitement de dilatation-érosion, il a donc été possible de proposer une couche livrable correcte d’un point de vue topologique, dans laquelle on retrouve clairement si le tronçon considéré est réservoir ou corridor.</gco:CharacterString>
