                  <gco:CharacterString>Type d'acquisition : polyligne numérisée par un opérateur unique (photo-interprétation assistée par ordinateur) ;

Échelle de numérisation : 1/2500 ;
Support de numérisation : orthophotographie géoréférencée (couleur) ;
Source du support : © Ortho Littorale V2 - Ministère en charge de l’environnement 
Échelle de prise de vue : 1/25000 ;
Résolution pixel de l'image : 50 cm ;
Date du support : 2011 ou 2012 selon les secteurs ;

Marqueur de la position du trait de côte : le contact entre la plage et la dune. Le long des secteurs en libre évolution, le pied de dune (secteur en érosion) ou la limite de végétation dunaire (secteur en accrétion) a été numérisé. Le long des secteurs artificialisés, le pied des ouvrages de protection a été retenu ;

Informations sur la numérisation : les indentations de la côte liées à la nature des marqueurs numérisés, à l'échelle de numérisation mais également à l'échelle de prise de vue et la résolution pixel des images aériennes, n'ont pas été prises en compte lors de la numérisation. Le trait de côte ainsi numérisé se présente sous la forme d'une polyligne lissée, permettant d'homogénéiser les tracés d'une même collection de traits de côte et limiter les valeurs aberrantes lors du calcul des vitesses d'évolution.

Incertitude de la position du trait de côte : ± 4,5 m</gco:CharacterString>
