    dct:description """Abstract: The Landsat Enhanced Thematic Mapper Plus (ETM+) is a sensor
        carried onboard the Landsat 7 satellite and has acquired images of the Earth nearly
        continuously since July 1999, with a 16-day repeat cycle. Landsat ETM+ image data
        consist of eight spectral bands (band designations), with a spatial resolution of 30
        meters for bands 1 to 5 and band 7. Resolution for band 6 (thermal infrared) is 60
        meters and resolution for band 8 (panchromatic) is 15 meters. Approximate scene size
        is 170 km north-south by 183 km east-west (106 mi by 114 mi). The Level 0R data
        product is reformatted raw data. Reformatting involves shifting pixels by integer
        amounts to correct for three effects: 1) the alternating forward-reverse scanning
        pattern of the Landsat ETM+ sensor; 2) the odd-even detector arrangement within each
        band; and 3) the detector offsets inherent in engineering design of the focal plane
        array. Pixels in L0R images are not resampled, nor are they geometrically corrected
        or registered, which means that the pixels are NOT aligned per scan line. The Level 1
        data product provides systematic radiometric accuracy, geometric accuracy by
        incorporating ground control points, while also employing a Digital Elevation Model
        (DEM) for topographic accuracy. Geodetic accuracy of the product depends on the
        accuracy of the ground control points and the resolution of the DEM used.""" ;
