Extension of the PEGELONLINE Infrastructure (EDIS)
EDIS provides the German Federal Waterways Administration with new ways to deliver critical measurement data faster and more reliably, for example in the event of flooding.
The ITZBund is a service center providing IT services to federal agencies in Germany. They operate the PEGELONLINE platform, an important infrastructure providing a broad range of hydrological measurement data collected along German waterways.
52°North provides consulting to evaluate event-based communication techniques for a more efficient delivery of (geospatial) information, such as measurement data, in real time. Our team specifically considers approaches to reduce data delivery latency and minimize server load using push-based communication protocols such as MQTT and AMQP. In addition to evaluating protocols, we investigate potential approaches for 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 and the Helgoland Sensor Web Viewer.
An important focus in 2024 was the testing of the initial version of the infrastructure by external partners. These tests provided valuable feedback on how to improve not only the system itself, but also important aspects such as user/developer documentation. Another important task was the work on supporting libraries and APIs that facilitate the discovery and exploration of available data streams, for example through a dedicated lookup service (“Dict API”). Finally, the project explored approaches for access control and redundancy, and improved the Sensor Web Viewer to better meet user requirements.
