El conjunto de datos GLS2005 es una colección de 9,500 imágenes satelitales ortorrectificadas de resolución media con hojas, recopiladas entre 2004 y 2007, que cubren las masas terrestres de la Tierra. GLS2005 usa principalmente datos de Landsat 5 y Landsat 7 con brechas completadas, y los datos de EO-1 ALI y Terra ASTER completan los huecos de datos.
Esta colección solo contiene el subconjunto de imágenes de GLS2005 del sensor ETM+ de L7.
