                  <gco:CharacterString>Cet outil est basé sur: 
−des modèles régionaux pour les corrections géophysiques (lorsqu’ils existent, correction de la marée, correction de la haute fréquence barotrope). 
− L’utilisation de nouveaux algorithmes de correction de la mesure pour éliminer ou réduire les effets dus à la présence du continent sur la mesure et les corrections, avec notamment, une procédure de sélection, de reconstruction et de lissage de corrections. Cette procédure consiste à définir un « critère d'editing » (i.e. l’ensemble de valeurs min et/ou max qui garantissent l’élimination de la plupart des mesures aberrantes) plus restrictif que le critère standard. Dans un second temps, une procédure statistique de contrôle qualité permet l’élimination de données aberrantes résiduelles. En parallèle, une méthode de reconstruction/lissage de corrections défaillantes par polynômes de Bézier est réalisée. 
Cette approche permet de récupérer un nombre significatif de mesures altimétriques proches des côtes. 
L'apport par rapport aux traitements standards est: 
− Une diminution du taux de mesures erronées ; 
− Une augmentation de la couverture en zone côtière ;
− La possibilité d'exploiter des mesures haute résolution le long de la trace (jusqu’à ~3 Hz soit 2 km).
