Zbiór danych Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010) zawiera dane o wysokości na całym świecie zebrane z różnych źródeł w rozdzielczości 7,5 sekundy łuku. Więcej informacji znajdziesz w raporcie dotyczącym zbioru danych.
Głównym źródłem danych dla GMTED2010 są dane SRTM Digital Terrain Elevation Data (DTED®, https://www2.jpl.nasa.gov/srtm/) (wypełnione) o rozdzielczości 1 sekundy łuku, pochodzące z NGA. W przypadku obszarów geograficznych poza obszarem pokrytym przez SRTM oraz w celu wypełnienia pozostałych luk w danych SRTM wykorzystano następujące źródła: dane DTED® inne niż SRTM, kanadyjskie dane o wysokości (CDED) w 2 rozdzielczościach, dane Satellite Pour l'Observation de la Terre (SPOT 5) Reference3D, dane National Elevation Dataset (NED) dla kontynentalnej części Stanów Zjednoczonych i Alaski, cyfrowy model wysokości (DEM) GEODATA o rozdzielczości 9 sekund dla Australii, cyfrowy model wysokości (DEM) z satelitarnego radaru i laserowego wysokościomierza dla Antarktydy oraz cyfrowy model wysokości (DEM) z satelitarnego radaru dla Grenlandii.
Ten zbiór danych zastępuje model wysokości GTOPO30.
