Javier Jimenez ShawIn <a href="https://mapstodon.space/tags/foss4ge2025" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#foss4ge2025</a> I was talking about Mercator projection, and what is the difference with "Web-Mercator"These images (at different zoom levels) show a loxodromic curve (at 45° N) in Web-Mercator (EPSG:3857) - that is a straight line in Mercator (EPSG:3395). In red the loxodromic or rhumline. In blue a straight line connecting the endpoints.(To reproduce it in <a href="https://mapstodon.space/tags/QGIS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#QGIS</a>, deselect "Clip features to canvas extent" for the affected layers as discussed in <a href="https://github.com/qgis/QGIS/issues/62654" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/qgis/QGIS/issues/62654</a>)<a href="https://mapstodon.space/tags/gis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#gis</a> <a href="https://mapstodon.space/tags/gischat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#gischat</a>
