EUSeaMap 2025 Broad-Scale Predictive Habitat Map for Europe - Confidence in Classification of Seabed Substrate Type (Habitat Descriptor)

Confidence in the classification of substrate type in the 2025 EUSeaMap broad-scale predictive habitat map, this was updated in the 2025 version.

Values are on a range from 1 (Low confidence), 2 (Moderate 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.

A report on the methods used in the 2025 version of EUSeaMap will be published in due course and reports on previous versions (v2016, v2019, v2021, v2023) are linked in lineage.
