Il set di dati GLS2005 è una raccolta di 9500
immagini satellitari ortorettificate a media risoluzione raccolte tra
il 2004 e il 2007 e che coprono le masse terrestri della Terra. GLS2005 utilizza principalmente dati Landsat 5 e Landsat 7 con riempimento delle lacune, con dati EO-1 ALI e Terra ASTER che riempiono
eventuali lacune nei dati.
Questa raccolta contiene solo il sottoinsieme delle immagini GLS2005
del sensore L5 ETM.
