How must I read the 8 bits of the status map?
In the status map the following bits are used for:
from MSB to LSB
Bit
NR 7 (MSB): radiometric quality for B0 coded as 0 if bad and 1 if good
Bit NR 6: radiometric quality for B2 coded as 0 if bad and 1 if good
Bit NR 5: radiometric quality for B3 coded as 0 if bad and 1 if good
Bit NR 4: radiometric quality for MIR coded as 0 if bad and 1 if good quality
Bit NR 7 - 4: coded as 0 for 'no data', missing lines, sea on VGT-S products, adjacent blind or defective MIR detectors, interpolated data, saturated data, negative data after atmospheric correction
Bit NR 3: land (code 1) or water (code 0), computed from the "Digital Chart of the Worlds"
Bit NR 2: ice/snow (code 1) , code 0 if there is no ice/snow, computed from thresholds from reflectances

Bit NR 7 - 4: coded as 0 when the algoritm could not generate output or when seaBit NR 3: land (code 1) or water (code 0), computed from the "Digital Chart of the Worlds"
Bit NR 2: ice/snow (code 1) , coded 0 if there is no ice/snow, computed from thresholds from reflectances
Bit NR 1: cloud/shadow or clear, coded as 1 if there is clouds or shadow, and 0 if not (clear sky)
Bit NR 0 (LSB): "qmir", radiometric quality for MIR band coded as 0 if bad and 1 if good
