The first latitude or longitude pixel (0,0) corresponds to the bottom edge of (5,5) in the snow cover field. Thus, for the along track direction, the total offset equals 5.5, which is the combination of the along track offset (=5) plus the new attribute HDFEOS_FractionalOffset_Along_swath_lines_500m_MOD_Swath_Snow (=0.5). And for the cross track direction, the total offset equals 5, which is the sum of the cross track offset (=5) plus the new attribute HDFEOS_FractionalOffset_Cross_swath_pixels_500m_MOD_Swath_Snow (=0). The next along track latitude or longitude pixel (0,1) corresponds to the bottom edge of (5,15) = (5.5,15). In the snow cover field, the along track increment equals 10. The next cross track latitude or longitude pixel (1,0) corresponds to the bottom edge of (15,5) = (15,5.5). In the snow cover field, the cross track increment equals 10.
