Why have a webGIS?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
www.searchMESH.net
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

Range of classification schemes, eg:
Biotope mapping to UK & Ireland classification scheme
Mapping of seabed features (facies)
Mapping of substrate types

Biotope MappingBiotope MappingSNH:
Mapping the distribution of benthic biotopes in Moray Firth
This type of mapping is often used in UK for studies of SACs

Delivering maps to end-usersDelivering 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)
www.searchMESH.net
webGIS SummarywebGIS Summary
MESH is delivering maps of seabed habitats classified using the standard nomenclature of the EUNIS habitat classification schemeMESH 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
