Description

The GLObal Bathymetric (GLOBathy) dataset, comprising data on over 1.4 million waterbodies globally, has been meticulously developed to harmonize with the widely recognized HydroLAKES dataset. Utilizing a sophisticated Geographic Information System (GIS)-based framework, GLOBathy constructs detailed bathymetric maps by integrating maximum depth estimates and geometric/geophysical attributes sourced from HydroLAKES. Ensuring data accuracy and reliability, GLOBathy undergoes stringent validation procedures involving 1,503 waterbodies and a diverse range of observed data sources. Consequently, GLOBathy stands as a robust and comprehensive dataset for hydrography and aquatic sciences, offering invaluable resources for researchers and professionals in these fields.
