UKASH Mosaic of Localised Maps integrates multiple ground-truthed habitat maps into a single, non-overlapping polygon dataset for the UK seabed. The Joint Nature Conservation Committee product preserves original classifications and provides standardised EUNIS and Marine Habitat Classification fields. This version was last updated on 2026-04-14.
Use Cases
- Marine spatial planning based on a unified, non-overlapping map of seabed habitats.
- Habitat conservation analysis based on standardised EUNIS and Marine Habitat Classification fields.
- Assessing data provenance for specific seabed areas based on the preserved source information for each polygon.
Strengths
- Integrates multiple localised habitat maps into a single, non-overlapping product.
- Preserves original classifications and source provenance for individual polygons.
- Provides standardised habitat classification fields (EUNIS v2007-11 and Marine Habitat Classification for Britain and Ireland v 22.04).
Limitations
- Coverage is limited to areas where localised habitat maps exist, leaving gaps.
- Column-level documentation is absent; field semantics must be inferred after download.
- Source maps vary in spatial and thematic detail, leading to potential inconsistencies.
Provenance
- Source
- Joint Nature Conservation Committee
- Collection Method
- Composite of multiple localised habitat map sources, with overlapping areas resolved by selecting the most reliable map according to set criteria.
