I have slight experience with ArcGIS, but am new to QGIS.

I'm trying to set the projection of my map, and I understand that this is done by altering the CRS (coordinate reference system) of each layer and/or the entire project.

When I right click a layer and select "Change Layer CRS", however, the visual representation of the map (the distortion) does not reflect the selected projection. My world map looks like it has a Robinson (or similar) projection, even if I select a Mercator CRS. The EPSG code in the lower right corner changes, as do the coordinates.

Example image - Mercator CRS

Setting the project CRS to the same projection does not help, nor does enabling on-the-fly projection.

My goal is to export the map to SVG, so the visual distortions are important.

Am I doing something wrong?


Please do not change the CRS of the layers. This will make your data unusable.

Instead enable On-the-fly-projection, and change the project CRS to your needs.

  • Thank you for your answer. I still do not get the distortions you would expect, though. I updated my answer with an image. – Oystein Oct 28 '13 at 13:04
  • OK, The NE data should be EPSG:4326, and for World Mercator use EPSG:3857. – AndreJ Oct 28 '13 at 13:15
  • Setting the source data (from NE) to the correct CRS did the trick. Thank you so much! – Oystein Oct 28 '13 at 13:19
  • Apparently, the SimpleSVG plugin does not handle on-the-fly projection. Is there a way to get the same result without using on-the-fly projection? Can I reproject a layer? – Oystein Nov 1 '13 at 9:30
  • Scratch that, just found 'qgis:reprojectlayer' in processing. It seems to work. – Oystein Nov 1 '13 at 9:37
