The AWI Basemap (version 2026) is a global basemap for GIS applications or web map viewers. The map is a rendered and shaded RGB version of the General Bathymetric Chart of the Oceans (GEBCO) grid with the International Bathymetric Chart of the Arctic Ocean (IBCAO) and the International Bathymetric Chart of the Southern Ocean (IBCSO) as polar datasets and with ice overlays from Antarctic Digital Database (ADD), Global Land Ice Measurements from Space (GLIMS) and Greenland Ice Mapping Project (GIMP). It is available in three projections, EPSG:4326 for the global map as well as EPSG:3995 and EPSG:3031 for the polar stereographic versions. The map comes in three different color schemes to be used for different purposes. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.997175"!
