• UK Stakeholders Workshop Natalie Coltman

Why have a webGIS?

• Effective management of the marine environment
  requires information on the spatial distribution
  and the quality of seabed habitats
• Seabed habitat data are not centrally accessible
• MESH aims to collate these data create unified
  seabed habitat maps

3
Which data?

• Data Metadata are collated by MESH
• Metadata data about data (what where when
  how)
• Data actual seabed mapping data
• MESH aims to
• Mobilise existing seabed mapping data through a
  searchable online Metadata Catalogue
• Collate seabed mapping data to create unified
  seabed habitat maps to be displayed
  on MESH webGIS

A website presenting interactive maps of seabed
habitats for NW Europe

• Zoom to areas of interest
• Control layers
• Query data attributes
• Generate reports
• Print maps

MESH Metadata catalogue

• Aims to mobilise existing seabed mapping data to
  the mapping community
• Lists over 1000 seabed mapping studies in NW
  Europe
• MESH metadata standard for habitat maps (ISO19115
  compliant)
• Template for data entry
• Available online via a simple or advanced
  search
• Updating metadata records this week

Original Habitat layer

• Seabed habitat maps
• Polygon maps
• Collated by MESH in Data Exchange Format
• Range of classification schemes, eg
• Biotope mapping to UK Ireland classification
  scheme
• Mapping of seabed features (facies)
• Mapping of substrate types

17
Biotope Mapping
SNH Mapping the distribution of benthic
biotopes in Moray Firth This type of mapping is
often used in UK for studies of SACs
18
Facies mapping
CEFAS Broadscale interpretation of seabed facies
between Hastings Varne in Eastern Channel
Common type of mapping in aggregate industry

Supporting data Acoustic

• Multibeam, single beam side scan useful to
  habitat mappers
• Outlines of areas of acoustic data on MESH webGIS
  to show where data exist
• MESH webGIS functionality also allows acoustic
  imagery to be displayed

Modelling

• Use physical data layers to predict habitat types
• EUNIS classes
• Marine landscapes
• Irish data to be incorporated soon

26
Presenting data

• Progress to date
• EUNIS colour scheme agreed
• Current issues
• How to display maps made at very different
  scales?
• Overlapping shapefiles
• Confidence assessments

Interoperability Signatures

29
Interoperability

• Link to NBN Gateway
• Species list for selected area
• Species diversity summary for selected area
• Web Mapping Services (WMS)
• Image of a map is returned from another mapping
  server
• Used to consume data from other websites

30
Delivering maps to end-users

• The MESH project is committed to making its final
  interpreted seabed habitat maps publicly
  available at no cost
• Data will be available for distribution to
  end-users for their local use
• Data will be available to other web sites and
  desktop GIS users via direct data links (WMS)

31
webGIS Summary

• MESH is delivering maps of seabed habitats
  classified using the standard nomenclature of the
  EUNIS habitat classification scheme
• MESH has developed standard data exchange formats
  for the efficient sharing of data
• Maps are presented to end-users in electronic
  format via a bespoke webGIS
• Data will be shared to maximise interoperability

32
Where next?

• Short term
• Gather feedback from Stakeholders, on the MESH
  webGIS
• New data upload mid-Nov
• Medium to long term
• Use established mechanisms for data collation,
  integration and dissemination
• Develop a strategy to maintain maps (beyond MESH)
