Since mining areas are typically of large geographic scale, equipping them with sensors is a challenge at high cost. One approach to keep these low is the enrichment and in some cases substitution of sensor data utilizing external sources, such as weather services. Against this background, this paper describes requirements for a solution that allows the use of external data sources to enrich or substitute sensor data for historic and real-time analysis. An architecture that supports this approach is presented. The architecture is implemented as a proof of concept for the purpose of demonstrating its abilities by the use case of land use regulations.enInternet of ThingsSystem ArchitectureMicroservicesSystem IntegrationExternal Data Sources10.18420/informatik2021-0631617-5468
