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 2023, 52°North focused on implementing the key elements of the real-time data infrastructure (data feeding, MQTT broker) so that the first external partners could start testing the offered data streams. Our team also began to address other conceptual challenges such as access control and increased reliability through redundancy. Additionally, we enhanced PEGELONLINE’s Sensor Web components to allow additional exploration and visualization of the access controlled data offered via the PEGELONLINE REST API.
One particularly important achievement in 2023 was the 3rd place in the German eGovernment competition in the category “Best Project Sustainability through Digitalization”.
