Running the VoronoiDiagrammer is producing some very weird results. Mainly huge strangely shaped polygons around the edges covering the whole globe as seen in the first image. The image below that is from qgis (same input data) and shows the output I was expecting. Anybody know what is going on?
Hi @dwastberg, I've never seen such a strange result generated by the VoronoiDiagrammer but I suspect that there is a bug in the transformer related to handling a coordinate system.
Anyway I would recommend you to send the point dataeset and a workspace which reproduces the issue to the Safe support team and ask them to take a closer look at this.

Hi @dwastberg Setting a Voronoi Radial Limit should get around this problem. Currently the VoronoiDiagrammer creates 3 polygons that extend beyond 90°N. If you reproject the points to local coordinate system then increase the Radial Limit accordingly.
