Extension of the PEGELONLINE Infrastructure (EDIS)
Investigating new approaches for real-time delivery of hydrological information
The ITZBund is a service center providing IT services to federal agencies in Germany.
They operate the PEGELONLINE platform, an important infrastructure that yields a broad range of hydrological measurement data collected along German waterways.
52°North provides consulting to evaluate event-based communication techniques to more efficiently deliver (geospatial) information, such as measurement data, in real-time. Our team specifically considers approaches to reduce the latency of data delivery and minimize server loads using push-based communication protocols such as MQTT and AMQP. In addition to evaluating protocols, we investigate potential approaches to structuring the delivered data, ensuring access control, supporting the development of client applications such as dashboards, and integrating event-based workflows into the existing IT infrastructure.
Our software engineers complement these activities by upgrading PEGELONLINE’s existing Sensor Web components. These include the current 52°North SOS implementation as well as the Helgoland Sensor Web Viewer.
The activities in 2021 mainly comprised upgrading the Sensor Web Server and the Helgoland Viewer, evaluating deployment options (e.g., using container technologies), as well as creating the first architectural approaches and prototypes in order to enable event-based data delivery.
