Sensor data is becoming increasingly important in the Dutch public sector. Smart cities initiatives, citizen science projects as well as nationwide sensor networks for specific tasks (e.g. environmental monitoring) have been increasing the amount of sensor data available. Being able to make sense of this data and combining data from diverse sources in applications such as digital twins is increasing the need to standardize sensor data.
In 2026 we organised a testbed on two implementation topics:
- Hosting a SensorThingsAPI server
A central SensorThings API server is set up in which all sensor data is collected and made available for analysis. For this purpose, a data model is developed based on the OMS standard that can support all used sensors. The server is set up, documented, and publicly demonstrated with relevant queries. The results, including lessons learned and any software, are shared openly. - Connect sensors to SensorThingsAPI server
Existing sensors are connected to a single central OGC SensorThings API server to promote interoperability within the public sector. Participants adapt their sensors or an intermediary solution to provide observations via this standard, validate the operation, and document their approach and lessons learned.
The results and recommendations of this Testbed are documented in a final report.
