Dear Nyall, Thank you so much for analyzing the issue and also thank you in advance for porting the fix to 2.18! I opened the sample project with 2.14 and I can confirm that the area values of both planimetric and ellipsoidic area calculations are very close for all features. It is very much

Hi Nyall, Thanks for the explanations. I should have read the explanations of the help text more closely. It explains it all. However, there still seem to be issues. Consider the following results below. First column is the result of $area, second column is area($geometry). Sometimes the
