 ABSTRACT = f'''
 The AWI Basemap is a global basemap intended to be used as a background for GIS applications or web map viewers like the DAM marine data portal. The map is a rendered and shaded RGB version of the current GEBCO grid with ice overlays from ADD, GLIMS and 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.
 AWI Basemaps are created by {__author__} ({__email__}), Bathymetry Group, Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany.
