The pilot will help ESPRESSO to identify gaps in the interoperability arrangements and validate the reference architecture to support the urban platform.

Houses in Rotterdam are built on wooden poles and these need to be kept wet, to avoid that they rot. Groundwater levels are measured at regular intervals using both sensors (currently 3) and human readings (approximately 2000 wells in the city manually measured). More sensors are planned so that more accurate, frequent, flexible measurements, less manual labour.

These sensor readings are sent and stored in the Data Lake for retrieval and analysis.

Sensor readings are read from the Data Lake using Sensor Things API (or SOS) and visualized in the existing CityGML based 3D model of the city.
