L'ensemble de données GLOBathy (GLObal Bathymetric), qui comprend des données sur plus de 1,4 million de plans d'eau dans le monde, a été méticuleusement développé pour s'harmoniser avec l'ensemble de données HydroLAKES, largement reconnu. En utilisant un framework sophistiqué basé sur le système d'information géographique (SIG), GLOBathy construit des cartes bathymétriques détaillées en intégrant des estimations de profondeur maximale et des attributs géométriques/géophysiques provenant d'HydroLAKES. Pour garantir l'exactitude et la fiabilité des données, GLOBathy est soumis à des procédures de validation rigoureuses impliquant 1 503 plans d'eau et diverses sources de données observées. Par conséquent, GLOBathy constitue un ensemble de données robuste et complet pour l'hydrographie et les sciences aquatiques, offrant des ressources précieuses aux chercheurs et aux professionnels de ces domaines.
