Global elevation and bathymetry on 2 arc-minute grid from the National Geophysical Data Center (NGDC). This dataset was original published in September 2001 and was revised to include correction to Caspian Sea area in April 2006. It contains improvements that include the blending of satellite altimetry with ocean soundings and new land elevation data from the Global Land One-km Base Elevation (GLOBE) project.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
