Aster instrument of the Terra satellite is also freely available for 99% of the globe, and represents elevation at 30 meter resolution... When land topography and bathymetry is combined, a truly Global Relief Model is obtained... ALOS provides since 2016 a global 1-arc second DSM free of charge... OpenTopography is a community access resource of high-resolution

Earth2014[править]
The Earth2014 global topography and relief model [17] provides layered topography grids at 1 arc-minute resolution. Other than SRTM30plus, #Earth2014 provides information on ice-sheet heights and bedrock (that is, topography below the ice) over Antarctica and Greenland

Sea depths[править]
To map some 140 million square miles of sea floor, the Seabed 2030 project is currently recruiting around 100 ships that will circumscribe the globe for 13 years. The team, united under the non-profit group General Bathymetric Chart of the Oceans (GEBCO)
