|Bathymetry and topography of the world|
Statement: Global estimated bathymetric and integrated bathy-topo relief models; 1 minute (~2 km) and 30 arc-second (~1 km) cell sizes
Abstract: Global ocean bathymetry estimated from sea-surface satellite altimetry (Geosat and ERS-1) measurements and constrained by ship depth measurements.
