[Qgis-user] CRS Errors

[Stewart Holt]

Yes, I have also noticed this. I think it started in some point rev of
3.10.x. I still see it in 3.12. Most of my work is using a WMS layer with
EPSG:3857. The ellipsoidal calculation would need to start with coordinates
in degrees and I wonder if it is passing the rectangular coordinates. I
think this either used to work or the default measurement used to be
cartesian and I never tried ellipsoidal because I am usually concerned with
distances of a few meters.
