This document is version two of the user requirements for SubCoast work package 3.5, it is
SubCoast deliverable 3.5.1. Work package 3.5 aims to provide a European integrated GIS
product on subsidence and relative sea level rise. The first step of this process was to
contact the European Environment Agency as the main user to discover their user
requirements.
This document presents these requirments, the outline methodology that will be used to carry
out the integration and the datasets that will be used. In outline the main user requirements
of the EEA are:
1. Gridded approach using an Inspire compliant grid
2. The grid would hold data on:
a. Likely rate of subsidence
b. RSLR
c. Impact (Vulnerability)
d. Certainty (confidence map)
e. Contribution of ground motion to RSLR
f. A measure of certainty in the data provided
g. Metadata
3. Spatial Coverage - Ideally entire coastline of all 37 member states
a. Spatial resolution - 1km
4. Provide a measure of the degree of contribution of ground motion to RSLR
The European integration will be based around a GIS methodology. Datasets will be
integrated and interpreted to provide information on data vlues above. The main value being
a likelyhood of Subsidence. This product will initially be developed at it’s lowest level of detail
for the London area. BGS have a wealth of data for london this will enable this less detialed
product to be validated and also enable the generation of a more detailed product usig the
best data availible. One the methodology has been developed it will be pushed out to other
areas of the ewuropean coastline.
The initial input data that have been reviewed for their suitability for the European integration
are listed below. Thesea re the datasets that have European wide availibility, It is expected
that more detailed datasets will be used in areas where they are avaiilble.
1. Terrafirma Data
2. One Geology
3. One Geology Europe
4. Population Density (Geoland2)
5. The Urban Atlas (Geoland2)
6. Elevation Data
a. SRTM
b. GDEM
c. GTOPO 30
d. NextMap Europe
7. MyOceans Sea Level Data
8. Storm Surge Locations
9. European Environment Agencya.
Elevation breakdown 1km
b. Corine Land Cover 2000 (CLC2000) coastline
c. Sediment Discharges
d. Shoreline
e. Maritime Boundaries
f. Hydrodynamics and Sea Level Rise
g. Geomorphology, Geology, Erosion Trends and Coastal Defence Works
h. Corine land cover 1990
i. Five metre elevation contour line
10. FutureCoas
