Overview - data flowsFocus on the following areas:

• Inputs - reporting

• Context of European water reporting

• Outputs – reporting services, web mapping applications,

web services, distributed systems

• Near Real Time data flows

Inputs – reporting

Data flow - reporting

Water Information System for Europe (WISE)

OUTPUTSINPUTS

Water Framework

Urban Waste Water

Nitrates Bathing

Floods

Drinking Water

OUTPUTSINPUTS

Features in Water Framework Directive (WFD)

WISE reporting

• Ensuring consistency, completeness and interoperability

• Distributed

• Large volume of information

• Achieve an agreed level of Quality Assurance

XML Schemas

WISE data preparation workflow

EEA/Commission

Support to the workflow

Guidance documents for GIS

• General guidance with general concepts and techncial descriptions

• Appendicies specific - 'living document'

Schemas QA

• Schemas limited through enumeration lists and types

• Schema validation tool

• Schema validation

• Complex schema validation rules

• Cross-schema check – uniqueness and referntial integrity

Spatial QA

• Documentation

• Automated code checks and ID cross-checks

• Tolopology checks still manual (operator using GIS tools)

• Metadata check

Direct support and feedback

• Workshops

• Helpdesk

• Feedback reporting and re-submission

Result

• Quality Assured data (compliant?)

• Tabular data

• Spatial

• Reference datasets

• Quality information

• Harmonised at European level

Outputs

Web reporting services

• XML imported and harmonised in database (schema to schema)

• Use of data views• Build reporting serviceon top using templates

Web mapping applications

• Spatial information available

• Presenting information in context – harmonisation, simplification, analysis, messages

EEA mapviewer

Web mapping services

• Web mapping applications thin clients to web services

• Web services encourage re-use, mash-up

ArcGIS.com

• Information re-use

• GeoPortal

• Market place

• Mash-ups

• ArcGIS.com demonstrates how easy it is to combine and deploy web services

Outputs – distributed system

Many issues to resolve!

• Harmonised map content

• Classifications e.g. risk

• The central portal needs to be able to handle fetching all these services in a production environment

• Need to have a system which can intelligently deal with urls which do not work for some reason

• Responsibilites for ensuring service delivery need to be defined.

• Define some protocol and registering and maintaining services

Near real time data flows

Eye on EarthWatches•Waterwatch - 2008•Airwatch – 2009•Noisewatch - 2010?•Climatewatch ?•Naturewatch ?...

Challenges for data flows

• Increased demand for near real time data

• More data• More timely data – faster• High level of interoperability• Integration between in-situ and satellite• Data re-use• Higher efficiency• Thematical independency • Improved expert access• Less resources to maintain multiple

flows• To be inline with SEIS

Near real-time data flows

• Ozone web

EEA and SensorWeb

• SWE – Sensor Web Enablement

• OGC standard

• Air Quality data flow proof of concept

• Industry support for software development – 52 North and ESRI

• http://www.pegelonline.wsv.de as example of outputs from SWE enabled dataflow
