[Qgis-user] QGIS3: measurements on projected space

[Tobias Wendorff]

Hi there,

Currently measurements are done on the ellipsoid the current CRS is
based on. That's not useful in all cases.

Question 1: Is it possible to freely choose an ellipsoid for measurements?

Question 2: Is it possible to measure on the projection screen and
not on the ellipsoid? Different applications require a measurement
on the projection and ellipsoid distance can give wrong results.

Question 3: Within ETRS89, there are formulas for distance correction
in national surveying (at least in Germany). It would be nice if you
could define a formula in the settings how the distance and areas are
calculated. I am currently using a workaround where I draw lines and
calculate the distances with a Python tool. That's pretty awkward.

Best regards,
Tobias
