Das GLOBathy-Dataset (GLObal Bathymetric) enthält Daten zu über 1, 4 Millionen Gewässern weltweit und wurde sorgfältig entwickelt, um mit dem weit verbreiteten HydroLAKES-Dataset kompatibel zu sein. GLOBathy nutzt ein ausgeklügeltes GIS-basiertes Framework, um detaillierte bathymetrische Karten zu erstellen. Dazu werden Schätzungen der maximalen Tiefe und geometrische/geophysikalische Attribute aus HydroLAKES integriert. Um die Genauigkeit und Zuverlässigkeit der Daten zu gewährleisten, durchläuft GLOBathy strenge Validierungsverfahren mit 1.503 Gewässern und einer Vielzahl von beobachteten Datenquellen. GLOBathy ist daher ein robustes und umfassendes Dataset für Hydrographie und Wasserwissenschaften und bietet Forschern und Fachleuten in diesen Bereichen wertvolle Ressourcen.
