  • A biotope analysis of Dundrum bay was conducted in 2015 as part of efforts to understand the distribution and extent of benthic habitats and associated marine life within the Murlough special area of conservation incorporating new and historical groundtruthing information alongside modern acoustic data. The map was originally presented in the Marine Habitat Classification for Britain & Ireland (http://jncc.defra.gov.uk/MarineHabitatClassification). This has been translated to the EUNIS habitat classification system for integration with other European datasets. For more information, see: AFBI, 2015. Bathymetric and Habitat Map for Murlough Special Area of Conservation and offshore, Northern Ireland. Report to the Department of the Environment.

  • Data holdings of polygonal habitat maps in European waters. Data are collated by EMODnet Seabed Habitats partners from a variety of source datasets and conformed and standardised into the portal's INSPIRE-compliant schema (for more information, please see https://emodnet-seabedhabitats.eu/def . Habitats are described in a variety of classification systems, including EUNIS (European Nature Information System), Habitats Directive Annex I and local/other classifcation systems. Ownership of the individual maps is retained by the original owners, for more information please see the individual metadata record tied to the map, which can be seen in the query response. Maps are available indivudually through EMODnet Seabed Habitats' "maplibrary" OGC service endpoints: For WMS (view) access to maps, please use https://ows.emodnet-seabedhabitats.eu/emodnet_view_maplibrary/wms? For WFS (download) access to open maps, please use https://ows.emodnet-seabedhabitats.eu/emodnet_open_maplibrary/wfs?

  • The results of the habitat mapping exercise were derived from aerial photography interpretation (API). The shapefiles produced are available to holders of OS MasterMap licenses. The habitat mapping dataset is held at Plymouth Coastal Observatory however, the Environment Agency is responsible for the GIS data as it was creating using their MasterMap licence. The survey extends from Portland Bill in Dorset to Avonmouth in Bristol and includes the Isles of Scilly. The landward limit of the survey varied but in general is determined by one of the following: Extent of aerial photography; Indicative tidal floodplain; Sites of Special Scientific Interest (SSSIs); Extent of coastal BAP habitats; 5m contour with a 200m landward buffer ; Inclusion of other target habitats. The habitat map was originally created using the Integrated Habitat Survey (IHS) classification originally developed by Somerset Environmental Records Centre. The classification was broadened to include all coastal habitats in South West England. The IHS classification had been substantially modified for the purposes of the habitat mapping. THIS was converted to EUNIS L3 by Ian Saunders at NE and forms the data NE provided to the JNCC as part of the MCZ project – Tranche 1. A MESH Confidence Score of 86 was assigned to the dataset based on the information given in the reports supporting the GIS. Orthorectified aerial photography used was flown to a scale of 1:5000. Photography was flown at low tide on a spring tide between the months of April and September to ensure maximum vegetation coverage. As a result of this and due to adverse weather conditions over some of the key tidal windows the whole project area was not captured in one block, but flown in stages between 2006 and 2009. Although ground-truthing was undertaken to support and validate the habitat map, not all areas were ground-truthed.

  • Broadscale habitat (EUNIS level 3) for the Mounts Bay recommended Marine Conservation Zone (rMCZ).Seabed texture polygons mapped using automatic segmentation and classification of acoustic data (MBES bathymetry and backscatter) and groundtruthing data from PSA analysis and image (stills and video).
