Present day Earth altimetry and bathymetry at 15 minute horizontal resolution.  Derived from the National Geophysical Data Center's TerrainBase Digital Terrain Model (v1.0).  The original dataset is at 5 minute resolution, and this has been averaged down to 15 minute resolution.  It is plotted here using a Mollweide projection (using MATLAB and the M_Map package).
