[PROJ] Installing PROJ on a Mac

Wed Nov 25 12:28:45 PST 2020

Chris,

Thank you for your reply.

I updated to 3.16, but the bug persists… I updated the GitHub issue tracker, even though it is closed; if no answer, I'll open a new QGIS ticket. One thing is sure: the user who opened the original ticket has still issues as well (Windows 10, QGIS 3.16).

The weird thing is that I can preview raster with the Winkel Tripel projection, but only part of it; as soon as the preview reaches the end of longitudes, the raster disappear (screenshots on the GitHub issue tracker).

As for my attempt at checking if PROJ was installed by typing 'proj', I had found it here:

https://github.com/dtutic/GDAL-1.10.1-wintri/blob/master/README.md

Anyhow, let's hope this bug can be fixed on QGIS side.

Thanks again for your input.

Cheers,

Christophe
