This is a demonstration for the benefit of combined datasets. Non-experts struggle interpreting InSAR data due to its odd measurement geometry, sometimes leading to incorrect conclusions on the deformation of objects. Great work has been done by several authors to address, rather than assess, this problem, in particular by Van Natijne (source).

Here we focus on the interpretability of the (line-of-sight, L2B) InSAR data from the European Ground Motion Service (EGMS). The InSAR data is represented as arrows, aligning with the measurement geometry and are colored according to the displacement magnitude. Furthermore, the arrows are clickable so that it becomes possible to inspect the underlying timeseries. Last but not least, the national point cloud (Actueel Hoogtebestand Nederland version 4) has been added to provide context for the InSAR measurements. After all, InSAR measurements are reflections from real objects. Thanks to the point cloud it becomes apparent that the EGMS point positioning is not perfect.

The scene displays the Waalbrug in Nijmegen, the Netherlands.

Special thanks goes out to the developer of Potree, Markus Schütz, which is used for displaying the point cloud, and the developers of three.js.
