Online Visualization of Streaming Data

The integration of streaming data into web mapping applications in combination with contextual information is currently drawing attention in geospatial research. This article discusses how to communicate streaming data in the form of a live mapping dashboard. We created our own prototypical online dashboard visualization for this purpose, tailored to be used in different contexts and roles, and discuss the advantages of the approach. The live mapping dashboard uses modern visualization techniques, including dynamic clustering and self-updating symbology. We validated our approach in the context of a use case in the field of forest-based supply value chains. We present the data flow from the data collection to harmonization, right up to the presentation of real-time data. The prototype is evaluated in continuously performed field tests.
