EUSeaMap (2023) Broad-Scale Predictive Habitat Map for the Caspian- Confidence in classification of substrate type

Confidence in the classification of substrate type in the 2023 EUSeaMap broad-scale predictive habitat map for the Caspian region. Values are on a range from 1 to 3 (1=low confidence, 2=medium confidence, 3=high confidence). Substrate type is one of the layers of information used to categorise physical habitat types in EUSeaMap; these layers of information are collectively known as 'habitat descriptors'. The substrate layer confidence was obtained from reclassification and standardisation of the confidence scores associated with each primary layer used to create the Substrate types layer.
