Set data GLS2005 adalah kumpulan 9.500 gambar satelit resolusi sedang yang telah diortorektifikasi dan diambil saat daun tumbuh, yang dikumpulkan antara tahun 2004 dan 2007 serta mencakup daratan Bumi. GLS2005 terutama menggunakan data Landsat 5 dan data Landsat 7 yang diisi dengan data EO-1 ALI dan Terra ASTER untuk mengisi setiap lubang data.
Kumpulan ini hanya berisi subset gambar GLS2005
dari sensor ETM+ L7.
