Geospatial IoT – The Need for Event-Driven Architectures in Contemporary Spatial Data Infrastructures
52°North recently published a joint paper in the isprs International Journal of Geo-Information.
The nature of contemporary spatial data infrastructures lies in the on-demand provision of geospatial information. Although recent applications identified the need to react to real-time information in a time-critical way, research efforts in the field of geospatial Internet of Things in particular have identified substantial gaps in this context. They range from a lack of standardization for event-based architectures to the meaningful handling of real-time information as “events”. The paper presents work in the field of event-driven architectures as part of spatial data infrastructures with a particular focus on sensor networks and the devices capturing in-situ measurements. The current landscape of spatial data infrastructures is outlined and used as the basis for identifying existing gaps that retain certain geospatial applications from using real-time information. We present a selection of approaches – developed in different research projects – to overcome these gaps. Designed for specific application domains, these approaches share commonalities, as well as orthogonal solutions and can build the foundation of an overall event-driven spatial data infrastructure.
