Exploring real-time geospatial data with SensorThings: from QGIS to QWC
.ical
2026-06-29 –, Auditorium

GIS works really well for most geospatial workflows, but when it comes to real-time or time-series data, things are still not very smooth. The OGC SensorThings API offers a way to access this kind of data through an open standard, but bringing it into everyday GIS workflows is not always straightforward.
In this talk, I’ll walk through a practical workflow for working with SensorThings data, from connecting to an API to exploring and visualising time-series data directly in QGIS using the OGC SensorThings plugin and the SensorThings Inspector.
From there, I’ll show how the same data can be brought into a web environment using QWC, and what needs to be considered when moving from desktop to web.
The focus is on the workflow itself: what steps are needed, what works well, what still feels a bit rough, and how real-time data can fit more naturally into open source GIS.
