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
![Page 3: MESH webGIS Habitat maps online at searchMESH/webGIS](https://reader035.vdocument.in/reader035/viewer/2022062305/5681587d550346895dc5dd86/html5/thumbnails/3.jpg)

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
Which data?Which data?

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)
