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 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.
Activities in 2022 were twofold. The 52°North team completed upgrading PEGELONLINE’s Sensor Web components. This included not only updating the 52°North SOS, but also customizing the Helgoland Sensor Web Viewer to provide optimized accessibility. The second large task was to create and implement an architecture for the event-based delivery of measurement data. After a comprehensive evaluation of architecture options for integrating incoming measurement data and system deployment, 52°North focused on the system’s implementation. First tests with selected users are planned for 2023.
