Habitats mapped as polygons representing broadscale habitats and biotopes, classified according to the JNCC Marine Habitat Classification (v22.04). Limitations include an estimated 2 m positional offset in the ortho-mosaics and limited ground‑truthing data. Habitats defined using expert judgement, with confidence assessed based on proximity to ground‑truthing data, data quality, and level of biotope assignment.

Habitats mapped as polygons representing broadscale habitats and biotopes, classified according to the Joint Nature Conservation Committee (JNCC) Marine Habitat Classification (v22.04). Limitations include an estimated 2 m positional offset in the ortho-mosaics and limited ground‑truthing data. Habitats defined using expert judgement, with confidence assessed based on proximity to ground‑truthing data, data quality, and level of biotope assignment.
