outline

• “Climate changes Spatial Planning” program• Data portal project (COM-1)• CESAR – database management system

3-4 october 2006 ADAGUC symposium KNMI

Climate changes Spatial Planning- main goals -

• Offer the Dutch government, the private sector and other stakeholders a clustered, high-quality and accessible knowledge infrastructure on the interface of climate change and spatial planning

• Engage in a dialogue between stakeholders to develop innovative integral approaches of spatial planning and land use that anticipate for climate change and contribute to a safe, sustainable and resilient socio-economic infrastructure in the Netherlands

Climate changes Spatial Planning- data type products -

• experimental data• data from monitoring • model output • (tailored) scenario’s • historic data• land-use maps• ……..

Climate changes Spatial Planning- data portal (1) -

Objectives COM-1 project:

• provide a central point (Virtual Data Centre) for project members and external users to access (consolidated) data products that are created by projects in adaptation, mitigation and climate scenarios.

• consolidation (in time and space) of data and model results (depending on user demands and in cooperation with the projects involved)

Climate changes Spatial Planning- data portal (2) -

What does this mean ?

• COM-1 provide services to assist program projects to make their scientific results available to users

• COM-1 does not provide a physical data centre, but integrates the data stores from the projects

• Projects have the freedom and obligation to manage their own data, COM-1 provides a common point of access

Climate changes Spatial Planning- data portal (3) -

What are the benefits ?

• Improved exchange of information between projects

• Economy of scale– Not every project has to develop its own access technology– This allows development of better access for users

• (New forms of) collaboration possible– Modern technologies enable better collaboration– Sharing not only data, but also models and tools

Climate changes Spatial Planning- data portal (4) -

the central point of contact (website) is a Catalog of data products

– shows what instances of data products are available– has a search that produces a list of data products that match

user-specified criteria– provides identification of the actual data products– is accessible through the internet

Catalog searches through metadata!Correct definition of metadata is essential !

CESAR database management system

CESAR: - consortium of 7 Dutch institutes- wide range of atmospheric and hydrological observations- long term monitoring (> 10 years)- host for measurement campaigns- partner and important data provider

in “Climate changes Spatial Planning” program

3-4 october 2006 ADAGUC symposium KNMI

CESAR - surface and tower observations -

3-4 october 2006 ADAGUC symposium KNMI

CESAR - Remote Sensing systems -

FM-CWDoppler polarimetric

3 beams

Radar planned on top of tower

3-4 october 2006 ADAGUC symposium KNMI

CESAR - database management system -

objectives:

- facilitate data exchange between members- harmonize data distribution- support access by (web) portals ( eg. COM-1 project)

user community:

- projects e.g. BSIK-KvR, CEOP, KODAC, BSRN..- individual researchers

3-4 october 2006 ADAGUC symposium KNMI

CESAR - database management system -

present status:

- data policy established - file format selected (netCDF)- filename convention defined- variable name based on CF-1 convention- metadata should comply with Dutch Core Set Metadata- access via web portal (and ftp for privileged users)

3-4 october 2006 ADAGUC symposium KNMI

to conclude:

- (definition of) metadata important ! (use standards)

- build/use generic interface between (meta)database and portal(s)

- provide conversion tools for data-providers?
