Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010) veri kümesi, çeşitli kaynaklardan 7,5 yay saniyesi çözünürlükte toplanan küresel yükseklik verilerini içerir. Daha fazla ayrıntıyı veri kümesi raporunda bulabilirsiniz.
GMTED2010'un birincil kaynak veri kümesi, NGA'nın SRTM Digital Terrain Elevation Data (DTED®, https://www2.jpl.nasa.gov/srtm/) (boşluk doldurulmuş) 1 yay saniyesi verileridir. SRTM kapsam alanı dışındaki coğrafi bölgeler ve SRTM verilerindeki kalan boşlukları doldurmak için şu kaynaklar kullanılmıştır: SRTM dışı DTED®, iki çözünürlükte Kanada Dijital Yükseklik Verileri (CDED), Satellite Pour l'Observation de la Terre (SPOT 5) Reference3D, ABD ve Alaska için Ulusal Yükseklik Veri Seti (NED), Avustralya için GEODATA 9 saniyelik dijital yükseklik modeli (DEM), Antarktika uydu radarı ve lazer altimetre DEM'si ve Grönland uydu radarı altimetre DEM'si.
Bu veri kümesi, GTOPO30 Yükseklik Modeli'nin yerini almıştır.
