The free and open-source GIS application QGIS offers a wide range of visualisation and export options. By the use of plugins one can extent these capabilities in many ways. This talk will show how trajectories, like movement recordings of humans, animals or machinery, can be turned into interactive 3D visualisations and embedded in a website using the qgis2threejs plugin. In this demonstration a map of a hiking trip will be compiled, then enriched with elevation data and photos, turned into a 3D map and finally exported as a webpage.

The free plugin qgis2threejs provides most of these possibilities with a focus on web export, and will be the main driver of this talk. But considering QGIS' native 3D view becoming more and more stable, its pros and cons will also be briefly discussed and shown.

Aspects that will be discussed include:
- Weighing up between resolution (texture and terrain) versus data size and performance
- Visualisation options for geo features
- Labeling options
- Decorations
- Customisation of the export outside the plugin
- Hosting the result on the web
