GTOPO30 ist ein globales digitales Höhenmodell (Digital Elevation Model, DEM) mit einem horizontalen Rasterabstand von 30 Bogensekunden (ca. 1 Kilometer).
Das DEM wurde aus mehreren Raster- und Vektorquellen mit topografischen Informationen abgeleitet. GTOPO30 wurde Ende 1996 fertiggestellt und über einen Zeitraum von drei Jahren in Zusammenarbeit mit dem Center for Earth Resources Observation and Science (EROS) des U.S. Geological Survey entwickelt. Die folgenden Organisationen haben durch die Bereitstellung von Finanzmitteln oder Quelldaten teilgenommen: die National Aeronautics and Space Administration (NASA), das United Nations Environment Programme/Global Resource Information Database (UNEP/GRID), die U.S. Agency for International Development (USAID), das Instituto Nacional de Estadistica Geografica e Informatica (INEGI) von Mexiko, das Geographical Survey Institute (GSI) von Japan, Manaaki Whenua Landcare Research von Neuseeland und das Scientific Committee on Antarctic Research (SCAR).
