GLS2005 veri kümesi, 2004 ile 2007 arasında toplanan ve Dünya'nın kara kütlelerini kapsayan 9.500 ortorektifiye edilmiş, yapraklı, orta çözünürlüklü uydu görüntüsünden oluşur. GLS2005'te ağırlıklı olarak Landsat 5 ve boşluk doldurulmuş Landsat 7 verileri kullanılır. EO-1 ALI ve Terra ASTER verileri, veri boşluklarını doldurur.
Bu veri kümesi yalnızca L5 TM ve L7 ETM+ sensörlerinden alınan görüntüleri ve yalnızca bu iki sensörün ortak olarak sahip olduğu 6 bandı (10, 20, 30, 40, 50 ve 70) içerir.
