Setting the Frame

• The coastal zones are of strategic

importance being home to a large

percentage of European citizens

• Exposure of the coastal zones to the

possible impacts of climate change

• The vulnerability of human and natural

systems on the coasts has increased

due to the continuing development and

built-up in the immediate vicinity of the

shoreline

Mitigation and adaptation

Adaptation to climate change

consists of initiatives and

measures to reduce the

vulnerability of natural and

human systems against

climate change effects

Mitigation is defined as the

technological change and

substitution that reduce

resource inputs and

emissions per unit of output

Indicator selection

• The selection of indicators is based on

the following criteria

• The indicators selected should be

based on existing indicator sets like

the 27 indicaters from the DEDUCE

project

• The indicators selected should have

relation to ICZM in a climate change

perspektive

(Indicator 2)

• Rate of development of

previously undeveloped

land (Indicator 3)

• Size, density and

proportion of the

population living in

the coastal zone (1.1)

• Value of residential

property (1.2)

Indicators - 2

• Coastal erosion (26)

• Geological stability

• Potential for Renewable

Energy

• Flooding (27)

• Number of people

living within ‘risk

zone’

• Area of protected

sites within an ‘at risk’

zone

• Value of economic

assets within an ‘at

risk’ zone

The software architecture

• General standards (ISO, OASIS)

• Web (W3C)

• Geospatial (OGC)

– WMS, WFS, WPS, Spatial SQL

• Open source versus commercial software

OpenSource Components

• Operating system (Linux)

• Database (PostgreSQL / PostGIS)

• Tomcat – application server

• Apache – Web server

• Geoserver – Geospatial server

• MapFish – Print server

• GeoExt (Web client)

– OpenLayers + extJS

Data

• Integrated Land-sea Database

• ENC data (S-57)

• National topographic maps

• Pan-European data sets from EEA

• Different access rights and data types

Client Interface

• Build using the GeoEXT system, based on Openlayers

and ExtJS system

• System has standard GIS components in terms of layer

tree and navigational functionalities

The WPS Processes

• The Web application creates an Execute command to

Geoserver

• The PostGIS database receives the spatial query and

creates the result view

• The database returns the view to GeoServer that renders

the result back to the client as WMS

• For further processing a WFS is made

Geoprocessing dialog

• For geoprocessing

execution, a process

dialog has been

created, with

predefined options

Conclusions

• Coastal areas are perceived as particularly vulnerable to

the impacts of climate change

• Knowledge based ICZM can contribute to as well climate

change adaptation as adaptation

• High quality integrated land-sea data are imperative for

reliable results

• An OGC compliant geoprocessing environment based on

open source can facilitate the dissemination and use of

the ICZM tools
