Haze and shadows do not count toward the cloud cover threshold.
UDM2.0 classification defines haze as follows (UDM 2.1 has one haze class):
- Heavy haze (Under UDM2.0’s definition): thin low altitude clouds, higher altitude cirrus clouds, soot and dust which allow fair recognition of land cover features, but not having reliable interpretation of the radiometry or surface reflectance.
- Light haze: thin low altitude clouds, higher altitude cirrus clouds, soot and dust which allow reliable recognition of land cover features, and have up to +/-10% uncertainty on commonly used indices (EVI and NDWI).
