O conjunto de dados GLS2005 é uma coleção de 9.500 imagens de satélite ortorretificadas de média resolução com folhas, coletadas entre 2004 e 2007 e que cobrem as massas terrestres da Terra. O GLS2005 usa principalmente dados do Landsat 5 e do Landsat 7 preenchidos com dados do EO-1 ALI e do Terra ASTER para preencher quaisquer lacunas.
Essa coleção contém apenas o subconjunto de imagens do GLS2005 do sensor L7 ETM+.
