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

Confidence in the classification of energy class in the EUSeaMap 2025 broad-scale predictive habitat map, as there were no changes to the biological zones in the 2025 update the confidence remains the same as the 2023 version.

Values are on a range from 1 (Low confidence), 2 (Moderate confidence), 3 (High confidence).

Energy level 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'. Confidence in the classification of an energy level at any location is driven by both the confidence in the values of the input variables, and the confidence in the classification based on proximity to, and uncertainty in, the boundary between classes (i.e. areas closer to a boundary between two classes will have lower confidence).

Layers are also available showing confidence in the values of the input variables used to model energy levels (kinetic energy at the seabed and wave exposure).

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.
