Promise functionality Sensor Web Enablement

• Harvest sensors on the Internet. Find the domain and location of sensors

• Contact the sensor and ask for (meta) parameters

• Define a selection of data and pre-process the data

• Receive the selection or instruct for periodic updates

• Automatic processing in models

• Request for alarm messages.

Experiences

• The standards are too open. For every domain a profile is required. (X, Y, dimensions, vocabularies)

• Trend to wireless communication is diametrally opposite the introduction of voluminous protocols.

• Relation with GML requires intelligent and highly paid developers

• Geo-objects and measurements are different objects. They follow different processes. Do not combine in one standard.

T

Successes• Models: meteo, river level, groundwater, can import SOS.

• GIS-layers (WMS) with sensors are available.

• Cooperation between institutes is increasing.

• New ideas for high resolution measurements are put in practice.

Jan Jellema Februar 2008

Work underway• Prediction curves

• Dynamic maps


Conclusions

• Better cooperation , better models, better predictions.

• Active and Informed civilians (Aarhus).

• Flexible and reliable support for urgent decisions.
