correctly even Grass has switched to the Geographic Lib method.</pre>

Hi Sebastian,<br>
AFAIK, GRASS GIS has not yet switched to the GeographicLib routines.<br>
See the feature request <a class="moz-txt-link-freetext" href="https://github.com/OSGeo/grass/issues/1235">https://github.com/OSGeo/grass/issues/1235</a>
not yet closed and the related PR
<a class="moz-txt-link-freetext" href="https://github.com/OSGeo/grass/pull/1283">https://github.com/OSGeo/grass/pull/1283</a> in draft status and not yet
merged.<br>

<pre style="font-family: courier, "courier new", monospace; font-size: 1em; white-space: pre-wrap; overflow-wrap: break-word; margin: 0px;">I must admit that, for me as a GIS operator, it is surprising and sounds like
bad news - so far surfaces have always been the same in various GIS software,
whether or not it was open-source or commercial (ArcGIS Pro). So from this
moment it will be that I will get different surfaces depending on the software
it was calculated? :(</pre>

Hi Jarosław,<br>
it seems to me the calculation of a polygon area on the ellipsoid
was always not the same in different GIS software.<br>
See, for example, these long threads at
