Goals National Sensor project
• Integrate Sensornetworks in the National GIS infrastructure
• Improve exchange between institutes
• Use SWE as input for models and applications
• Cooperation between domains
• Cooperation between organisations
• Cooperation between scale of monitoring
• Cooperation between old-actual-prediction data
Why Standardisation?
Trend:
Utrecht, zaterdag 19 april 2008Sensornetwerken5
1.        Cooperation between domains:
Meteo
Soil Humidity
Engineering
Groundwater
Surface Water
Agriculture
Safety
2. Cooperation between organisations
Pumping station
Water Authority
Province Ministery
Other 
country
European 
Union
Pump
Oil pressure
Fuel
Maintenance
Waterlevel in
Discharge
Waterlevel out
Volumes/year
Floodings
Pollution
3. Spatial scale
• Overview: Remote Sensing
large volumes, periodical
• National Weather stations , LOFAR
continue, ADSL, wired locations
• Regionaal: Field sensors 
many, wireless, periodical, small volumes
• Buildings Wired and powered sensors
Engines Continue, often no storage
Laboratories
Many domains

Conclusion 1: 
Many organisational restrictions
• Privatisation restricts Meteo Institute 
free access Groundwater Institute
• Contract dependencies Hydraulic Institute
• Missing responsibility Soil Humidity
• Lagging Public education No understanding for
statistics, valdidation
Statement: Free exchange between institutes and authorities
Utrecht, zaterdag 19 april 2008Sensornetwerken13
Conclusion 2: 
Trend in field sensors contrary to SWE
Trend: smaller and wireless sensors
• Batteries limit energy consumption
• Wireless protocol requires compact messaging
Possible in 3-4 year??
• WIMAX protocol
• Alternative energy supply         wind -- bio -- sun
Utrecht, zaterdag 19 april 2008Sensornetwerken14
Conclusion 3 SWE has to much freedom
Detailed profiles for each domain required
• Names of measurements, processes and definitions
• Unit of measurements
• Axes, positive-negative
• Symbols and colors
Conclusie 4 Applicaties
• Ready made applications needed for
- Data input
- Statistical processes
- Data fusion and generalisation
- Graphical and visualisation tools
• Loose relation with location and GML
Optional relation with GML
