Sensordata (IoT) is widespread in both private and public sector. However, making use of sensordata across different sectors and applications is challenging - in particular with respect to a geospatial application across different use cases. This encompasses both enviroment/climate sensors, like water-level sensors to smart-building monitoring and water pipe sensors. An interdisciplinary team from diverse sectors is working towards building national standards, an open architecture and implementing proof-of-concepts on a national sensorhub for sharing streams and archives of sensordata in Norway. The team builds upon the very successful open data ecosystems (SDI) that exists in Norway for standardized geospatial data. The project is funded from a range of partners including municipalities, the mapping authority and the maritime ports of Norway. The working group includes open source tech expertise on sensor technology alongside user and demand expertise from the different sectors. This talk will focus on the technological advances made from the team both on software and architecture. There will be particular focus on the open architecture and software prototyping that has been developed in the working group. Both of which will be available under an open license.
