EUSeaMap (2019) Broad-Scale Predictive Habitat Map - Confidence in classification of EUNIS/full-detail habitat types
Confidence in the classification of the EUNIS/full-detail habitat types in the EUSeaMap (2019) broad-scale predictive habitat map.
Values are 1 (low confidence), 2 (moderate confidence) or 3 (high confidence).
The final habitat type is classified by overlaying several layers of information; these layers of information are collectively known as 'habitat descriptors'. Habitat descriptors differ per region but include:
Biological zone
Energy class
Oxygen regime
Salinity regime
Seabed substrate
Riverine input
The confidence in the classification of the habitat type is taken as the minimum of the confidence in all of the relevant habitat descriptors at that location.
Confidence values are also available for each habitat descriptor and input data layer.
Detailed information on the modelling process for the 2016 is found in the EMODnet Seabed Habitats technical report and its appendices (Populus et al, 2017, link in Resources). We are working on an updated report for the 2019 version.
Created by the EMODnet Seabed Habitats project consortium.
It is important to note that a habitat type confidence score is only relevant to that particular level of the classification system. For example, a cell of A3.1 high energy infralittoral rock with ÔÇÿlowÔÇÖ energy class confidence, ÔÇÿmoderateÔÇÖ biozone confidence and ÔÇÿhighÔÇÖ substrate type confidence would have an overall ÔÇÿlowÔÇÖ confidence. However, moving up the hierarchy to EUNIS level two (A3 infralittoral rock) removes the energy class; therefore, the confidence of the EUNIS level two habitat type would only consider the ÔÇÿmoderateÔÇÖ biozone confidence and ÔÇÿhighÔÇÖ substrate type confidence, resulting in an overall ÔÇÿmoderateÔÇÖ confidence.
