LANDSAT TM L1g flag bands: The LANDSAT TM cloud and land classification flags as used for the AE correction (i.e. downscaled to the AE correction grid). This product is provided in BEAM DIMAP format.
The coding of the cloud classification flag is listed in the following table:
Table 3.1. Cloud classification flags
Name | Value | Description |
---|---|---|
F_CLOUD | 0 | Pixel was finally specified as cloudy (if all flags below are set) |
F_BRIGHT | 1 | Brightness flag (set if TM3 < BT) |
F_NDVI | 2 | NDVI flag (set if NDVI < NDVIT_CLOUD, with NDVI = (TM4 - TM3)/(TM4 + TM3)) |
F_NDSI | 4 | NDSI flag (set if NDSI < NDSIT, with NDSI = (TM2 - TM5)/(TM2 + TM5)) |
F_TEMP | 8 | Temperature flag (set if TM6 < TM6T_CLOUD) |
The coding of the land classification flag is listed in the following table:
Table 3.2. Land classification flags
Name | Value | Description |
---|---|---|
F_LANDCONS | 0 | Pixel was classified as land |
F_LOINLD | 1 | Pixel was classified as inland waters (currently no algorithm implemented and set to false) |
F_NDVI | 2 | NDVI flag (set if NDVI < NDVIT_LAND, with NDVI = (TM4 - TM3)/(TM4 + TM3)) |
F_TEMP | 8 | Temperature flag (set if TM6 > TM6T_LAND (summer), TM6 < TM6T_LAND (winter)) |
F_ICE | 16 | Pixel was classified as ice (currently no algorithm implemented and set to false) |
