International Digital Elevation Model Service (IDEMS)

A newly developed International Digital Elevation Model Service (IDEMS) is now available under the umbrella of the International Gravity Field Service (IGFS) of the International Association of Geodesy (IAG). IDEMS provides a focus for distribution of data and information about various digital elevation models, including spherical-harmonic models of Earth’s global topography and lunar and planetary DEM. Related datasets, such as representation of Inland Water within Digital Elevation Models, and relevant software which are available in the public domain are also provided.
