The terms and conditions below apply to all the data sets provided on ESRI Data & Maps. Index of /mgg/global/relief/ETOPO2. ETOPO1 Global Relief. ETOPO1 is a 1 arc-minute global relief model of Earth's surface that integrates land topography and ocean bathymetry.
It was built from numerous global and regional data sets, and is available in "Ice Surface" (top of Antarctic and Greenland ice sheets) and "Bedrock" (base of the ice sheets) versions. Historic ETOPO2v2 and ETOPO5 global relief grids are deprecated but still available. NCEI has utilized the ETOPO1 Global Relief Model to calculate the volumes of the world's oceans and to derive a hypsographic curve of Earth's surface.
Color Image of Earth A color shaded-relief image of Earth from ETOPO1 Ice Surface, created by NGDC (now NCEI), is displayed above. Atlantic-centered and Pacific-centered wall posters of ETOPO1 are now available. Available Versions of the Grid ETOPO1 Ice Surface: Grid of Earth's surface depicting the top of the Antarctic and Greenland ice sheets.ETOPO1 Bedrock: Grid of Earth's surface depicting the bedrock underneath the ice sheets.

NGDC/MGG-Global Land One-km Base Elevation Project (GLOBE Topography) Other Sources and Reviews of DEMs: The Global Land One-km Base Elevation Project (GLOBE) Task Team was established by the Committee on Earth Observation Satellites.
It was part of Focus I of the International Geosphere-Biosphere Programme - Data and Information System. For more information, please see A Brief History of GLOBE in the project report.

Es gibt in der wissenschaftlichen Literatur keine allgemeingültige Definition der Begriffe digitales Höhenmodell (DHM) und digitales Geländemodell (DGM).
International gebräuchlich ist auch digitales Terrainmodell (DTM). Repräsentierte Oberfläche eines DOMs (rot) und eines DGMs (türkis) Das digitale Oberflächenmodell (DOM) (engl. digital surface model) repräsentiert die Erdoberfläche (Grenzschicht Pedosphäre - Atmosphäre) samt aller darauf befindlicher Objekte (Bebauung, Straßen, Bewuchs, Gewässer usw). Hingegen repräsentiert das digitale Geländemodell (engl. digital terrain model) die natürliche Erdoberfläche (vgl.
Li u. a. 2005, AdV 2004, siehe Abbildung). Die Definitionen des Begriffes digitales Höhenmodell (engl. digital elevation model) unterscheiden sich stark bezüglich der repräsentierten Oberfläche.
