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

The software architecture

• General standards (ISO, OASIS)

• Web (W3C)

• Geospatial (OGC)

– WMS, WFS, WPS, Spatial SQL

• Open source versus Commercial software

6

7/13/2011

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 (DK, N, B, UK)

• Pan-European data sets (e.g. 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

Geoprocessing dialog

• For geoprocessing

execution, a process

dialog has been

created, with

predefined options

The WPS Processing

• The Web based client 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

• A WFS is created for further processing

Items for discussion

• Is the Open source geoprocessing environment mature enough

for authority use ?

• Does the commercial software satisfy todays requirements for

transparancy in geoprocessing ?

• Is the use of WFS satisfactory for geoprocessing purposess ?

• Is WCS a ‘forgotten’ standard due to lack of business interest ?
