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.
In 2025, our team focused on improving the infrastructure developed to ensure productive operations in the years to come. We also released the initial version of the EDIS Dict API. This service provides comprehensive functionality to help users find relevant time series and MQTT data streams. Other important aspects included investigating enabling redundancy of MQTT brokers and improving the usability of the multi-sensor client based on the Helgoland Sensor Web Viewer.

Our cooperation with the ITZBund on the EDIS project will extend beyond 2025. Following a successful bidding process, 52°North was awarded a follow-up framework contract that will run until 2028.
